August 2026 Office Hours

Kan Herb Company — August Office Hours: The Liver & Liver Formulas

This session, hosted by Greg Pepping and led by Darren Huckle, focused on one of TCM's most central organs: the liver. Darren opened with a reframe — rather than seeing the liver as the "problem child" responsible for 100 diseases, he encouraged practitioners to see it as the organ of flow, expression, planning, and engagement with life. He walked through lifestyle factors that harm or help the liver (overstimulation, unmet desires, poor diet, lack of movement and expression), and practical patient recommendations like journaling, heartfelt conversation, dance, and exercise.

The bulk of the session covered a progression of liver formulas organized by pattern, from simple Qi stagnation through blood deficiency, yin deficiency, liver fire, and liver harassing other organ systems — with formula differentiation tips throughout. Darren closed with a reminder that the liver is highly responsive and regenerative, and that giving it consistent attention through lifestyle, emotion, and herbs yields real results.

Chapters

0:12 — Welcome & Kan Overview
Greg introduces the session. Kan has been manufacturing nearly 300 formulas in-house in Santa Cruz since 1987. Office Hours are held the second Wednesday of every month.

2:33 — The Liver: Soothe or Move
Darren introduces the session theme. The liver governs flow, expression, planning, and coursing. When bound, it causes irritability, stagnation, and eventually harasses other organ systems. Key lifestyle supports: movement, expression, gratitude, flexibility, and community.

11:10 — Liver Qi Stagnation: Signs & Symptoms
Classic signs include irritability, sighing, mood swings, craving crunchy foods, premenstrual tension, and breast tenderness. The liver begins bullying the stomach, spleen, and intestines — causing reflux, bloating, cramping, and appetite changes.

15:00 — Liver Flow & Bupleurum Soothe Liver
Liver Flow (Shu Gan San) for mild binding and early organ harassment. Bupleurum Soothe Liver (Chai Hu Shu Gan San) for stronger stagnation with emerging blood stasis and fixed pain.

17:29 — 4 Cold Extremities (Si Ni San)
The archetypal "open up the liver" formula. For patients who internalize everything — cold hands and feet, unexpressed emotions, an outward calm masking internal intensity.

19:30 — Release Restraint (Yue Ju Wan)
For six stagnations — Qi, blood, phlegm, fire, food, and damp — all binding simultaneously. Good when the liver is overwhelming the digestive system and everything feels stuck.

20:50 — Free & Easy Wanderer / Relaxed Wanderer (Xiao Yao Wan / Jia Wei Xiao Yao Wan)
A mixed excess-deficiency formula for liver blood deficiency plus liver Qi stagnation attacking the spleen. Darren's "balloon" metaphor: when blood is full, the system has resilience; when depleted, it contorts under pressure. Relaxed Wanderer adds heat-clearing herbs for more agitation and irritability.

27:00 — Si Wu Tang: Liver Blood Deficiency
A nourishing "hug for the liver." For tension, vulnerability, poor boundaries, timidity, and difficulty planning — all signs of a depleted general.

29:00 — Gracious Power (Yi Guan Jian): Liver Yin Deficiency
For deeper depletion — burnout, restless irritability, crispy edginess. Softens and nourishes liver yin without the aggressive opening of Chai Hu.

31:00 — Liver Fire: Quell Fire (Long Dan Xie Gan Tang)
When prolonged stagnation generates heat — explosive anger, redness, aggression, hypertension, herpes, hepatitis. Clear the fire first, then open the liver.

34:29 — Liver Spasm & Tightness
Tight liver Qi causes spasmodic pain throughout the body — intestinal cramps, uterine cramping, acid reflux, difficulty swallowing. Tong Xie Yao Fang (Soothe Spasms) highlighted for intestinal spasm and acute indigestion.

37:06 — Pediatric Q&A: Ear Infections & Otitis Media
Minor Bupleurum (Xiao Chai Hu Tang) as a gentler alternative to Quell Fire for babies and children with recurring ear infections. Bonus tip: warm onion in a sock applied to the ear as a home remedy.

39:00 — Calm Dragon (Chai Hu Long Gu Mu Li Tang)
For liver harassing the heart and disturbing the shen — emotional lability, panic, PTSD, agitation, withdrawal. Anchoring and grounding with mineral shells.

41:00 — Gastrodia Wind Relief (Tian Ma Gou Teng Yin)
For liver yang rising — headaches, dizziness, hypertension-type patterns, tinnitus, insomnia, over-alertness.

43:00 — Dispel Stasis in the Mansion of Blood (Xue Fu Zhu Yu Tang)
For long-term liver Qi binding the chest into blood stasis — angina, rib pain, deep emotional wounds that have moved from the Qi level to the blood level.

45:00 — Liu Wei Di Huang Wan & Closing Thoughts
Six Flavor Tea Pills to emolliate, soften, and nourish the liver for the tired, wired, under-resourced patient. Darren closes with encouragement to "love the liver up" — it is one of the most regenerative and responsive organs in both Western and Chinese medicine.

47:25 — Q&A: Post-Nasal Drip & Stress-Induced Asthma
Post-nasal drip with cough: Pe Min Kan Wan plus Wise Judge (Sha Shen Mai Dong Tang) to moisten the lungs; Ban Xia Hou Po Tang for throat phlegm and unexpressed liver Qi. Liver-invading-lung asthma: wood-metal harmonizing formula from CMS, or combining Liver Flow with Cordyceps or Wise Judge.
