What They Came In For: IBS
After years of unpredictable digestion and no real answers, Josh L. came to Root and Branch looking for something different. What changed everything? A custom herbal formula tailored to his body—and a treatment plan that listened. This is the story of how his gut finally started to settle.
When Your Gut Stops Making Sense: Finding Rhythm Again After IBS
When Josh L. first came in, he was a little embarrassed to talk about what was going on. He had already been to his primary care doctor, a GI specialist, and a nutritionist. He had Googled more than he wanted to admit. He had tried cutting out gluten, dairy, coffee, and sugar. He had tried probiotics, peppermint capsules, and digestive enzymes. Nothing really helped.
Still, the idea of describing his digestion out loud to another stranger felt like a lot. "I just don't want to be that guy," he said. "You know, the one who won't shut up about his stomach. But I’m here for help, so here we go."
His symptoms had been going on for over two years by then, long enough to start shaping how he lived. Some days were fine. Other days, he would eat something perfectly normal, grilled chicken, a salad, a bowl of rice, and suddenly find himself doubled over with cramping and urgency an hour later. Sometimes he was constipated for days. Other times, everything ran straight through. He could not predict it. Could not track it. He just always had to be near a bathroom, just in case.
The GI doctor told him it was IBS and ruled out anything more serious. Which was reassuring, but also, in its own way, deflating.
"It kind of felt like getting diagnosed with a shrug," Josh told us. "Like, well, it's not cancer, so we can try some stuff and maybe it’ll help."
By the time he came to Root and Branch, he was tired. Tired of second-guessing every meal, of pretending that everything was fine when it wasn't. He didn't necessarily expect Chinese medicine to fix it. He figured it couldn't hurt to try something different.
What IBS Actually Looks Like From the Inside
Irritable Bowel Syndrome is one of the most common digestive diagnoses in the United States. Current estimates suggest it affects somewhere between 10 and 15 percent of adults, though many people who have it never end up with a formal diagnosis. It is what clinicians call a functional disorder, meaning the plumbing looks fine on imaging and biopsy, but the function is off. The gut is doing the wrong thing at the wrong time, and no one can quite point to why.
For patients, that framing can feel maddening. You know something is wrong. Your life is arranged around bathroom proximity. You have stopped eating at restaurants, stopped taking road trips, stopped trusting your own body to behave in public. And then a specialist tells you the tissue looks healthy, the bloodwork is unremarkable, and there is no structural problem to repair.
The standard recommendations that follow usually include fiber adjustments, a low-FODMAP elimination diet, stress management, and sometimes medications like antispasmodics or low-dose antidepressants to modulate gut-brain signaling. These approaches help a meaningful number of people. They also leave a meaningful number of people stuck. Josh was in the stuck group.
Listening for the Pattern
We started, as we always do, by listening. We asked about his symptoms, yes, and also about his story. About how long things had felt off. About how stress landed in his body. About the nights his gut kept him awake, and the strange way everything tightened during even minor decisions. In Chinese medicine, IBS is not a single condition with a single fix. It is a pattern, and patterns are about relationships between systems rather than isolated symptoms.
We looked at his tongue, felt his pulse, examined his abdomen, and asked questions that might have seemed unrelated. About his energy levels across the day. About how well he slept. About whether he could actually relax after meals or whether he ate standing up, half-distracted, between obligations. His answers formed a recognizable shape. The digestive system was stuck in a state of overreaction. Underneath that reactivity was a quieter picture of weakness and cold. His gut had lost its rhythm and was swinging too far in both directions, clenching when it should have been releasing, and releasing when it should have been holding steady.
In classical terms, this is a version of a disharmony between the Liver system and the Spleen system. The shorthand is useful mainly because it names what a lot of IBS patients experience but rarely have framed for them. One part of the body is generating pressure and tension. Another part, the part responsible for steady digestion and transit, is too depleted to hold its ground. The two systems start working against each other, and the bowel is caught in the middle.
Why Stress Changes Your Stool
Most IBS patients already know, intuitively, that stress affects their digestion. What they often have not been told is why, in mechanistic terms, that relationship is so strong.
The gut has its own nervous system, the enteric nervous system, which contains roughly 500 million neurons. It runs largely independently, but it is in constant two-way conversation with the brain through the vagus nerve. When the body perceives threat, even low-grade chronic threat like deadline pressure or financial worry, the autonomic nervous system shifts into sympathetic dominance. Blood flow redirects away from the digestive organs, bowel motility changes, and visceral sensitivity increases, meaning the same amount of gas or stool that would have been unremarkable now registers as pain.
In people with IBS, this stress-response wiring tends to be set on a hair trigger. The gut overreacts to normal stimuli. A medium-sized meal feels like an overwhelming load. A mild emotional stressor produces a cascade of cramping. Over time, the pattern reinforces itself. The gut becomes more reactive. The person becomes more vigilant about the gut. Vigilance increases sympathetic tone. Sympathetic tone worsens the gut.
This is the loop Josh was caught in when he arrived. His digestion was not failing because he was eating the wrong foods or because he was unlucky to be wildly allergic to things he liked to eat. It was failing because his whole system had been living in a state of alarm for so long that the gut had forgotten how to do its job calmly.
What the Herbs Were Actually Doing
That is where the herbal medicine came in.
We formulated a custom blend for him, something to gently warm the center of his digestion, regulate the bowel, and calm the overactivity without suppressing it. The formula included herbs that support digestive function, herbs that soften tension in the smooth muscle of the gut, and herbs that address the underlying cold and depletion we had identified during the intake. The goal was to meet his body where it was and help guide it back toward its own regulation.
Well-formulated Chinese herbal medicine works differently from the single-compound pharmaceutical model most patients are used to. A formula is built as a system. One or two herbs address the main pattern. Others support the primary herbs, moderate their effects, or direct the action toward specific systems. The overall formula has properties that no individual herb in it would have alone. For a condition like IBS, where multiple systems are out of sync with each other, this kind of layered approach matches the problem.
There is also a growing body of research looking at how Chinese herbal formulas affect the gut specifically. Some formulas have been shown to modulate the gut microbiome, reduce inflammatory markers in the intestinal wall, and influence serotonin signaling in the enteric nervous system. The mechanisms are still being mapped, but the clinical results have been consistent enough that several formulas are now recognized in integrative gastroenterology as viable options for functional bowel disorders. In many ways, modern clinicians are catching up to what classical doctors have known for hundreds or sometimes thousands of years.
Josh's formula became the foundation of his care. It changed as he changed, adjusted every few weeks to respond to how his symptoms shifted. It was the steady thread that helped his gut relearn consistency.
The Role of Acupuncture
We paired the herbs with acupuncture, though in Josh's case the herbs were doing most of the heavy lifting. Acupuncture has a well-documented effect on autonomic nervous system balance. Treatment sessions tend to shift patients out of sympathetic dominance and into parasympathetic tone, which is the state in which digestion actually happens. For someone whose gut has been operating on high alert for years, time spent in that shifted state is therapeutic in itself.
Several clinical trials have examined acupuncture for IBS specifically, with generally positive results on symptom scores, quality of life measures, and reductions in abdominal pain. The effect sizes are modest in most studies, but the safety profile is excellent and the benefits accumulate over a series of treatments.
For Josh, acupuncture was the component that helped him unwind the emotional undercurrent driving his symptoms. He would often come in wound tight and leave loose-limbed and quiet. Over time, that quieter state started to become more available to him outside the treatment room.
What Changed, and How Fast
Within the first week, his urgency calmed. Within two weeks, his bowel movements had begun to normalize. Meals felt less like a risk. The background panic around food started to dissolve.
"I didn't realize how loud my gut had become until it got quiet," he told us one day. "I feel like my whole system is less reactive now. Like I finally have a little space between what I eat and what happens next."
Clinical improvement in IBS looks like a less reactive gut. The person develops a more neutral relationship with their own digestion, and food stops being a threat assessment and starts being food again. The specific symptoms matter for the overall timeline of improvement and where we decide to measure outcomes (things like bowel frequency, urgency, and pain), but the underlying shift is about the nervous system and the digestive system learning how to trust each other again.
Patients will even describe this shift in the clinic when they talk about feeling more in relationship with their bodies, and less adversarial with eating and digesting. We hear less about how “my stomach hates me” and more about how they have agency and choice again.
Josh's symptoms did not disappear overnight. Over the course of a few months, they stopped dominating his life. Over the next 3 months, he started trusting his digestion again. And by the end of a year thinking about his health and his digestion through a Chinese medicine lens, he was living day to day without even considering whether this thing he was about to eat was a trigger food. IBS had become a thing he once dealt with and not a defining fact of his experience.
If You Are Still Looking
What Josh came in for was relief. What he got was something more useful in the long run: clarity about what his body was actually doing, digestive resilience that held up across different kinds of days, and a sense of being understood by the clinical approach he had chosen.
If you are struggling with digestive issues that have an unknown cause, you are not alone, and you are not imagining it. The statistics on IBS are substantial. The gap between what the standard workup reveals and what patients actually experience is one of the most common frustrations in outpatient medicine. That gap is where Chinese medicine often does its best work, because it is set up to describe what is happening in functional and relational terms rather than structural ones.
If you have been told there is nothing else to try, we would gently offer that there might be. We don't just treat IBS as a diagnostic label. We treat the pattern underneath, and we treat the person carrying it. Your body is always telling a story. We are here to help it tell a different one.

What They Came In For: Frequent Colds
Catching every cold that comes around? Chinese medicine looks beyond immunity to the deeper question of constitutional strength and how to rebuild it.
Sarah M. came in because she caught colds constantly. Every six weeks or so, sometimes more often, she'd come down with something. She'd tried vitamin C, zinc, elderberry, and more sleep, but the pattern continued. She wanted to know why her immune system seemed so much weaker than everyone else's.
This is one of the most common concerns people bring to our clinic. It's also one of the most misunderstood, because the problem usually isn't the immune system itself.
Modern immunology frames immunity in terms of defense: how well does your body identify and destroy pathogens? From this perspective, frequent illness suggests a failure of surveillance or response, and the solutions follow logically. Stimulate the immune system, give it more resources, train it to fight harder.
Chinese medicine asks a different question: does your body have the resources to maintain its boundaries in the first place?
In classical terms, we talk about wèi qì 卫气, often translated as "defensive qi." Wèi qì isn't a standing army waiting to fight invaders. It functions more like the integrity of a container. When wèi qì is robust, the boundary between inside and outside holds, and wind and cold and damp don't penetrate easily. When wèi qì is weak, the boundary becomes porous.
Wèi qì is produced by the body's deeper metabolic processes, rooted in what we call the spleen and lung systems. These aren't the anatomical organs but functional networks responsible for extracting energy from food and distributing it through the body. When those systems are depleted, wèi qì suffers and colds come easily.
This was the pattern we saw with Sarah. She ran cold, especially in her hands and feet. Her digestion was sluggish, with bloating after meals and low appetite in the morning. She carried a tiredness that sleep didn't fix. Her pulse was thin and soft, and her tongue was pale and slightly puffy with a thin white coat. All of this pointed to qì deficiency, particularly in the spleen and lung networks.
Treatment focused on building her up. We used acupuncture to support the spleen and lung systems, choosing points that strengthen qì production and consolidate the body's surface. We prescribed an herbal formula based on Yù Píng Fēng Sǎn 玉屏风散, Jade Windscreen Powder, from the Dānxī Xīnfǎ 丹溪心法 (c. 1347), which addresses this pattern of weak protective qì and susceptibility to wind invasion.
We also talked about how she was living. She skipped breakfast and ran on coffee until noon. She exercised hard several times a week despite being exhausted, because she felt she should. In classical terms, she was spending more than she was earning.
Chinese medicine takes the arithmetic of energy seriously. You have a certain amount of qì available each day, and you spend it on movement, digestion, thought, emotional processing, immune function, and repair. If you consistently spend more than you take in, your reserves erode. Sarah didn't need to overhaul her life, but she did need to stop draining herself unnecessarily. Eating breakfast, scaling back intense exercise, and resting when tired would make a real difference.
Over the following months, the colds became less frequent. When she did catch something, it resolved faster. Her energy improved and her digestion settled.
This is what constitutional treatment looks like. We weren't boosting her immune system in the way that phrase usually implies. We were helping her body rebuild the underlying vitality that makes healthy immune function possible. Sarah still comes in occasionally for a tune-up when life gets demanding, but she's out of that cycle of constant illness. Her body holds its ground now.
What They Came In For: Constipation
Bill came in with chronic constipation — sometimes going three or four days without a bowel movement. Nothing he’d tried worked. With acupuncture and herbs, we helped his body regain rhythm and ease. Within a few weeks, his digestion was regular again — and with it, his comfort, clarity, and mood.
Bill came in because he was tired of feeling stuck. Literally.
For the past few years, his digestion had gotten slower and slower. At first, it just meant less regularity — a missed day here and there, nothing dramatic. But it crept up on him. By the time he showed up at the clinic, it wasn’t uncommon for him to go three or four days without a bowel movement. When things did move, it was slow, dry, and incomplete.
“It’s like my body just forgot how to do it,” he said.
He was 68, semi-retired, and pretty active — still walking his dog daily, still making coffee for his wife every morning. But this one issue had become a constant source of discomfort. He felt heavy after meals, bloated in the evenings, and often had to turn down food he would’ve enjoyed just to avoid the aftermath. He wasn’t in pain exactly, but he was never quite at ease.
His doctor told him it was normal at his age — just slow motility. He’d been told to drink more water, eat more fiber, and take stool softeners as needed. None of it really helped.
“It’s not like I’m eating cheeseburgers every day,” he joked. “I’m doing the right things. But my gut’s just not cooperating.”
When the Basics Aren’t Enough
Bill had already done the basics. He drank plenty of water. Ate oatmeal most mornings. Took a daily magnesium supplement. Tried psyllium husk, probiotics, even prune juice.
But none of it shifted his baseline. He still only had a proper bowel movement once every three days — sometimes longer. And the longer he went without one, the worse he felt. Foggy. Sluggish. Like things were backing up in more ways than one.
From a Chinese medicine perspective, constipation isn’t just a plumbing issue — it’s often a reflection of deeper imbalances. In Bill’s case, his pulse was thin and wiry, his tongue pale and dry, and his abdomen slightly firm on the lower left. What we saw was a pattern of dryness and depletion, layered with a bit of tension.
This wasn’t a case of excess heat or inflammation — it was about a system that didn’t have enough moisture, movement, or rhythm to keep things going. Over time, the body had lost momentum. The digestive fire had dimmed, and the fluids that should help guide waste downward weren’t doing their job.
Gentle, Steady Treatment to Restore Rhythm
We started Bill on a once-weekly acupuncture schedule to begin. The goal wasn’t just to get him moving once — it was to retrain his system to expect regular movement again.
We used points on the abdomen and lower back to stimulate the Large Intestine 大肠 (dà cháng) pathway and restore the downward flow. We added supportive points to nourish the Spleen 脾 (pí) and Kidney 肾 (shèn) systems — the internal organs responsible for transforming food into usable energy and fluid.
We also gave him an herbal formula customized for his constitution: one that moistened the intestines, gently promoted peristalsis, and tonified the underlying systems that had weakened over time. No harsh purgatives. No laxative effect. Just a slow restoration of internal balance.
After the first two weeks, things started to shift. Bill was going every two days without needing to think about it. The bloating had eased. His appetite was better.
After a month, he was having regular, easy bowel movements almost daily. No discomfort. No urgency. Just simple, quiet function.
A Return to Normal
“I never thought I’d feel this much joy over taking a normal crap,” he laughed.
But the truth is, this kind of change runs deep. Constipation isn’t just about digestion — it affects energy, mood, sleep, even mental clarity. Bill had started to feel more like himself again: less irritable, more comfortable in his body, and no longer thinking about his gut all day long.
Chinese medicine treats constipation not by forcing the body, but by reminding it how to move. Through acupuncture, herbs, and a steady rhythm of care, Bill’s system began to remember. And once it did, everything else started flowing again too.
What They Came In For: Long Covid
Months after a mild case of COVID, Thomas K. still wasn’t himself—fatigue, brain fog, and unrest that wouldn’t let go. At Root and Branch, a custom herbal formula and targeted acupuncture helped his system reset. This is the story of what it’s like to finally begin coming back to life.
“I just want to feel like myself again.”
That’s what Thomas K. said when we asked him what brought him in. Then he paused.
“And the truth is, I’m not even sure I remember what that feels like.”
He’d had COVID ten months earlier. It was his second time getting it—the first had been over a year prior, and he’d recovered easily. A few days of fatigue, some sniffles, and then life went back to normal. He was vaccinated. He’d done everything “right.” So when he got it again, and it started as a mild case, he wasn’t too worried.
But this time, the recovery never came.
The fever passed. The test turned negative. But the fatigue stayed. Not the kind you push through with coffee or a good night’s sleep—the kind that settles into your bones. He started needing to lie down in the afternoon. Sometimes his chest felt tight—not dangerous, just off. His brain felt foggy, like he was trying to think through static. He forgot words. Simple tasks took longer. His mood got flatter. His sleep got worse.
He kept waiting to bounce back. But the weeks turned into months, and nothing changed.
He’d had all the tests. Labs normal. Lungs clear. “You're just stressed,” one provider said. Another called it post-viral syndrome and offered antidepressants. He wasn’t against medication. He just didn’t feel like anyone was really listening to what was happening in his body.
That’s when he found his way to Root and Branch.
What he wanted was simple: clarity, energy, and the ability to trust his body again.
We started with the big picture. When did the fatigue hit hardest? How did he feel after meals? How had his digestion been since the illness? What about temperature regulation? Sweating? Focus? Anxiety? We looked at his tongue, felt his pulse. Beneath the surface, his system told a familiar story: a body still caught between recovery and defense. Weakness at the core. Stagnation in the chest. A nervous system on edge.
We explained how long COVID presents, through the lens of Chinese medicine, as a pattern of post-viral depletion and dysregulation. Energy isn’t just “low”—it’s blocked. The body isn’t just tired—it’s stuck in a pattern it can’t exit.
So we built a treatment plan to help guide it out.
At the center of that plan was a custom herbal formula—one tailored to nourish the body’s energy without overstimulating it, to open the chest, support lung and spleen function, and gently recalibrate the nervous system. Not a stimulant. Not a sedative. Just medicine that knew how to listen to what the body actually needed.
He took it twice a day, every day. And we adjusted it often—because as his body changed, the formula needed to change too.
We paired it with acupuncture designed to support his recovery on multiple levels: points to regulate his sleep, clear the lingering heaviness in the chest, restore cognitive clarity, and rebuild his sense of groundedness. After each session, he’d say the same thing: “I didn’t know I could feel this calm anymore.”
After three weeks, his fatigue began to shift. Not all at once—but there were longer stretches of clarity. Mornings that started easier. Fewer naps. More consistency. His brain fog started to lift. He could read again, focus on a conversation without drifting.
After six weeks, he said, “I feel like I’m finally climbing out of something.”
We continued to treat the fluctuations—days where his energy dipped again, or sleep became fragile—but overall, the direction was steady. Upward. Back toward himself.
What Thomas came in for was his energy.
What he found was recovery—and something more: a renewed relationship with his body, one built not on pushing through, but on paying attention.
At Root and Branch, we’ve worked with many long COVID patients, each with a slightly different picture. Some come in with chest tightness. Others with digestive distress, insomnia, hair loss, anxiety, or relentless fatigue. No two cases are identical—but the approach is always the same: track the pattern. Treat the root. Support the whole person.
If you’re living with long COVID symptoms that just won’t let go, know this: there is still healing available. It might not be fast. But it can be real.
And we’re here for the long arc of it.
The Power & Poise of Chinese Herbal Medicine
Travis Cunningham L.Ac.
Where I live in Portland, Oregon, many people share an interest in natural medicine. There are two Chinese medicine schools in town, a Chiropractic school, a Massage school, the oldest Naturopathic school in the country, and a medical school which specializes in Integrative Medicine. With such an abundance of natural medicine to choose from, why would someone pick a medicine that does not draw its roots from local soil? Wouldn’t it be better to choose medicine that is grown, stored and processed here? Why should people give Chinese herbal medicine a shot?
All of these questions are valid. And as a Chinese medicine practitioner, I have been asked them many times. The answer lies within the uniqueness of assessment, diagnosis, and treatment that Chinese herbal medicine can offer. This begins with the medicine’s focus on relationship.
Understanding the Relationship
The focus of a Chinese medical assessment is not based on the physics of what is happening in your body. This assessment is actually more concerned with understanding the relationship between your component parts (e.g. your organs, tissues, or bones). Our understanding is expressed using a kind of symbolic language. These symbols are taken from activities and movements that ancient people observed within nature and then observed that those natural processes had an apparent likeness to activities within the human body.
Knowing the History
The Chinese Medicine understanding of combining herbal remedies is backed up by thousands of years of writing and experimentation. The older writings that exist on the various topics of herbal medicine also have hundreds of years of commentary and discussion by physicians of past and present. In a very real sense, Chinese herbal medicine has close to two thousand years of peer review. This fact alone may suffice to make it worthy of consideration for modern people.
Defining the Symbol
Natural experiences like heat, cold, dampness, dryness, and wind, are described as they appear in a person’s body presentation. Shaking, for example, with its sudden appearance and disappearance, tremor and vibration are caused by wind. The ancients observed the air suddenly moving and gusting, shaking the leaves of the trees and blowing debris along the ground, and they carried this experience to their understanding of human physiology.
Symbols such as Wood, Fire, Earth, Metal and Water, were also chosen to emphasize patterns of functional movement within the body. The Lungs and the Large Intestine both descend and consolidate, as is the movement of Metal in nature. The Lungs breathe in air (descent), and consolidate the essence of air into nourishment for the body. The Large Intestine descends the stool and consolidates moisture for optimal elimination. Every major organ is looked at by a similar likeness with a corresponding movement in nature.
The ancient Chinese found that when these movement patterns were happening harmoniously and in just the right amount, a person was happy and healthy. While, a disharmony or mismanagement of these movement patterns led to disease. When these nature-based symbols are used together in an evaluation, a Chinese medicine practitioner can form a type of diagnosis called a pattern. A pattern reflects the relationship of harmony and disharmony within a person’s body.
Finding the Pattern
All Chinese medical treatment, whether acupuncture, moxibustion, cupping, gua sha, or herbal medicine is done to address a person’s pattern. This is different than targeting the person’s disease (as is done in biomedicine). If we seek the destruction of an illness we require a force to eliminate it. If, however, we seek to restore a pattern of functional movement, all that we require is a guide. This guide can be less forceful, but it must be precise. The cultivation of precision is the skillset of the Chinese medical practitioner. This skillset is practiced through a careful differentiation of the pattern.
Lets look at an example:
Two people catch a cold. Person A, has chills and fever, a slightly irritated sore throat, a headache on the sides of their head, and itchiness in the ears. Person B, has chills and fever, an intensely swollen and painful throat, and is sweating profusely.
Analysis:
Biomedically, these people may have the same virus attacking their systems. But in Chinese medicine, what is important is the pattern that such an illness presents within the individual. And in the example above, the pattern is different.
In person B, the intensely swollen, painful throat and profuse sweating indicate a heat pattern. In person A, the sore throat is less severe. The itchiness in the ears and location of the headache indicate that the illness has reached a different pathway (the Gallbladder or Shao Yang layer). The Chinese medical treatment will be different for each case, as it will tailor to the individual’s pattern.
As you can see, the pattern not only tells us about the disease, but also the relationship between the disease and the person’s constitution. This relationship is given a symbolic name with the terms discussed above (Example pattern: wind-heat invading the exterior). Treatment is given to principally address this relationship, and help assist the person restore their health (Example treatment principles: clear heat, vent wind, secure the exterior).
Choosing the Formula
To execute the above principles in the form of a treatment, a formula is chosen. A formula is a set of procedures that follow the direction of a treatment principle. In acupuncture, a formula is a list or set of acupuncture points, and the needling techniques of each point. In Chinese herbal medicine, a formula is a set of herbs given at a particular dosage and frequency of administration.
Chinese herbal medicine studies not only the effects of an individual herb, but pays particular attention to how that effect changes when herb A is combined with herb B. Herbs in combination can emphasize certain functional principles, or unlock new actions entirely.
The hot herb Fu Zi (Aconite) can be used to treat invasive cold patterns like neuropathy of the limb, by warming and dispersing the cold influence. But Fu Zi can only become a tonic for the heart, when it is combined with other sweet herbs like Gan Jiang (Dried Ginger) and Zhi Gan Cao (Prepared Licorice Root). In this case, Gan Jiang and Zhi Gan Cao also act to nullify the toxicity and harshness of Fu Zi, making the decoction or tea, safe to drink. While if you were to take Fu Zi by itself, the remedy might actually be dangerous.
Treating the Person
The strength of using Chinese medicine ultimately stems from the medicine's focus on treating the person. The perspective that Chinese medicine comes from is a view that believes in health as a natural phenomena. Health doesn't need to be forced, it can simply be encouraged. And with the right encouragement, a natural state of health and happiness can resume. Ease is, after all, easier than disease.
