Some mornings after a night’s rest, my body is unhappy. My lower back aches, my legs are stiff and creaky, and I am annoyed. Since I am an older man, I guess this is to be expected; I am tired and worn down and the cold rain that fell overnight has crept into my bones. My self-diagnosis is Wind Cold Damp with underlying deficiency. I know just the remedy, Plum Flower® Solitary Hermit Teapills™ /Du Huo Ji Sheng Wan (MW# 3343), also available as an extract/granule. This is my ‘go-to’ formula for my patients, and myself, for this condition.

Essential Formulas Worth a Thousand in Gold (Bèijí qiānjīn yàofāng備急千金要方) published in 652CE by the famous Tang-dynasty physician, Sun Simiao.
Mayway Herbs’ variation*, known as Solitary Hermit Teapills™, is mainly used to treat Wind and Damp invading the Channels with underlying Kidney Deficiency. It is ideal for treating Wind Cold Damp Bi with any underlying deficiencies of the Liver and Kidneys, Qi, and/or Blood. Since the lower back is the House of the Kidneys, the keynote is low back pain. Because Damp and Cold tend to settle downwards, the patient may complain of intermittent, chronic, aching pain and weakness in the low back, hips, knees and/or legs, heavy and painful sensations at fixed spots in the lower body, as well as coldness, stiffness, spasm, pain and possible numbness in the legs, potentially with difficulty walking. Symptoms may be exacerbated in cold and damp weather, or during weather changes. This may be accompanied by certain deficiency signs including cold intolerance, tremors, dizziness, palpitations, shortness of breath, fatigue, pale complexion, and others. The tongue may be normal or pale or showing other signs of deficiency, and the pulse may be thin, thready, weak, slow, or deep.
The fourteen herbs in the formula address both the symptoms and the root cause, strengthening the body's vital energy and dispelling pathogenic factors. They work together to Dispel Wind-Cold-Damp, Tonify the Liver and Kidneys, Tonify Qi, Nourish Blood, and stop Bi pain. This prescription is often combined with acupuncture and/or moxibustion to improve lumbar function, mobility, and reduce the aches and pains in the lower back, knees, and joints.
An analysis of the formula reveals these combinations and relationships:
- Du huo and Sang ji sheng are the Chief herbs used to dispel Wind and Dampness, nourish Blood, harmonize Qi, and activate Meridians.
- Huai niu xi, Du zhong, and Shu di huang serve as Ministers to nourish the Liver and Kidneys and strengthen the tendons and bones.
- Niu xi also serves as a Guide to direct the actions of the herbs to the Lower Jiao.
- Fang feng and Qin jiao serve as Deputies to expel Wind, Cold, and Damp throughout the body.
- The remaining herbs act as Assistants: Chuanxiong, Dang gui, and Bai shao nourish and activate Blood circulation. Dang shen, Fu ling, and Gan cao invigorate Qi and strengthen the Spleen, energizing Qi and Blood. Rou gui dispels cold and relieves pain and Zhi gan cao is the Harmonizer.

The dosage guidance for this formula is 8 teapills, 3 x per day, although 12-16 pills may be taken in the initial phases of therapy, and then reduced to a maintenance dose as the formula takes effect. Administer half an hour before or one hour after eating. May be used long-term for several weeks to several months. In cases of chronic deficiency, Solitary Hermit™ Teapills may be used safely over the course of several years, along with additional constitutional remedies. Monitor for signs of Deficiency Heat since the formula is intended to dispel Cold in the Channels and lower back.
This classic Chinese herb formula is very effective when Wind Cold Damp attacks a patient with aches and pain, who is constitutionally deficient. Since many of your patients will experience these symptoms, especially in the fall and winter, Solitary Hermit Teapills™ should be in every practitioner’s herb dispensary.
