This is an important Chinese herbal formula that regulates the blood circulation in the lower half of the body while also stimulating the fluid metabolism. Together, these actions effectively address temporary pain and swelling of the joints in the legs, muscle atrophy, and numbness in the legs.

Other indications include aches and pains associated with a sensation of burning that seems to arise from the bones and tendons on the skin or surrounding joints on the legs or feet.

If the “damp-heat” undermines the flow of qi and blood through the leg, the outcome can be muscle weakness or atrophy in the legs.

While this formula is often used for red swelling in the legs, it is equally beneficial for “damp heat” in the lower abdomen. The most common benefit is regulating the fluids of the female reproductive system when there is vaginal discharge that is thick, yellow, and with a foul fishy odor.

Adult Dosage

    Eagle Herbs is now supplying a 2 gram “little spoon”. (Please wash and dry before using.)

    An “average dose” is 10 grams per day of the granules or 20 capsules.

    A Big Dosage for Short-lived but intense issues: 3 little spoons (12 capsules) twice a day.

    A Smaller Dosage for Lingering low-grade concerns: 2 little spoons (8 capsules) twice a day.

    If you are very sensitive to medicines: start out low (1/2 little spoon or 2 capsules) once per day, and raise the dosage each day.

    We find that people find the right dosage for themselves: what feels good for them and they get the results they are looking for.

Your order will last approximately this long:

  • 100 grams powder (capsules or powder): 8 to 25 days
  • 200 grams powder (powder only): 19 to 56 days
Child’s Dosage

The dosage is 1/2 teaspoon (1 little spoon or 4 capsules) per 50 pounds of weight. This quantity should be taken 2 to 3 times daily.

This is not an especially tasty formula. If you’re interested in giving this formula to a child, you may need to hide it in juice or food. It’s available in capsules too, but they may be too large for children to swallow. The capsule size are 500mg, which is a very common size for dietary supplements.
