What does it do?

Supports Leg Comfort

Think what it would be like to be able to go for brisk walks again, free of discomfort. Or go up and down a flight of stairs with vigor. Think what it would be like just to go get the mail without the experience feeling like a trek up Mt. Everest. And think what a relief it would be going to the bathroom and having a strong urination without stopping and starting in fits.

Many people believe living with body discomfort and weakness is just a part of the normal aging process. But if you have joint discomfort and your lower extremities prevent you from living life to the fullest, our classic formula, DampClear™ may help.

Ancient TCM Formula Clears Heat and Removes Dampness

DampClear is an herbal traditional Chinese medicine (TCM) remedy. Chinese medicine doctors have historically dispensed this formula (known as Si Miao San in TCM) to regulate blood flow in the lower extremities; metabolize fluids; and support normal joint function.

Although Damp-Heat theory dates back several centuries, it applies more than ever to modern lifestyles. One major reason Damp-Heat develops is diet. Too much sugar, greasy and fatty foods (and sometimes spicy food, depending on your constitution) can lead to internal Damp-Heat.

When Damp-Heat accumulates in the body, according to TCM theory, it particularly affects the sensitive, hollow spaces, i.e. the joints. That's because Damp-Heat impedes the flow of Qi. Think about when you're on a cross-country or international flight. Your joints get stiff and discomforting from sitting for so long. Your circulation and life energy force--Qi--is impeded. (Just as you feel stiff in the lower body from flying, Damp-Heat first affects the lower extremities.) The result of this can manifest as redness around the feet, ankles or knees.

Dampness obstructs harmonious Qi flow and causes stiff joints and heavy limbs. As for Heat, it dries up the fluids and injures Yin. When fluids dry, it causes a vicious cycle, leading to more Dampness.

How Does DampClear Work?

The first herb in the formula, Huang Bo (Amur Cork Tree Bark) purges fire and resolves toxicity. Cang Zhu (Atractylodes Rhizome) dries dampness and strengthens the Spleen.

Next in the formula is Niu Xi (Achyranthes Root), which tonifies the Liver and Kidneys, and dispels stasis and unblocks the Channels. Yi Yi Ren (Coix Seed) clears heat and strengthens the Spleen and leaches out dampness.

These four herbs work synergistically to clear Damp-Heat. There's good reason that the classic formula for this is known as "four marvels pill.".

Does Research Support DampClear?

Many clinical studies have been conducted to evaluate the usefulness of the Si Miao San formula in supporting healthy uric acid metablism and supporting joint health with positive outcomes.1-3.

How do I use it?

The standard dosage for Dampclear™ is 5 tablets each time, taken 2 to 3 times daily with or before meals. One bottle lasts 11 to 17 days. The dose may be doubled for a quicker and stronger response as needed. Consult your practitioner for precise dosage recommendations based on body weight and other factors.

Dampclear™ has a mild action and therefore it usually takes time before its effects become apparent.
