  • This formula is the “go to” for the signs of heat and is said to have something of a detoxifying benefit.
  • It usually is used only for 10 days for the effects to help and then discontinued. After 10 days you can go back on it again.
  • It may also cause loose stools or diarrhea if taken too much or too long.

Toxicity in Chinese medicine means evidence of redness such as rashes.  Specifically, it is said to eliminate “damp-heat” from these two channels. Because heat rises and damp is a heavier fluid we often find more damp indications lower in the body and more heat indications higher in the body.

Dampness that descends within the Liver channel often manifests with weeping, oozy sores. Because this damp is warm or hot (we call it “damp-heat”) these weeping sores usually arise on a red base.

Thick coat with optional red dots (indicating heat).

Oozing clear fluids means dampness, redness means heat. These sores can arise anywhere that the Liver channel dominates such as the genitals, the ribs and flank, and the lips. (The Liver channel isn’t just one discrete channel, but it has tributaries, like a river with streams feeding into it.)Because the Liver is particularly sensitive to stress, we find that these symptoms of damp-heat are all aggravated by stress. However, in the absence of a thick yellow tongue coating, one should choose other formulas. A thick tongue coating is defined as one that is so thick, you can’t see through it to the tongue body beneath. Many tongues are only thick in the rear, this would suggest that *maybe* this is a good formula for you.

It focuses on symptoms of toxicity located along the trajectory of the Liver and Gallbladder (acupuncture) channels. The Gallbladder channel goes down the sides of the legs and the Liver channel goes through the genital area as it ends near the big toe. Because of the very cold nature of this formula it should be only be used for brief periods of time – such as 5-10 days.Heat rising in the Gallbladder channel causes headaches that arise on one side of the head, potentially arising from the point GB 21 (at base of skull above neck), extending to the acupuncture point GB 14 (right above the mid-point of the eyebrow), and zig-zagging across the temple and side of the head. Because this heat has some dampness in it too, it may additional cause a sense of muzziness or brain fog associated with the headache addressed by this formula.

NOTE while not life-threatening, sores that are fluid-filled on a red base may be communicable and care should be taken to avoid passing it on to others. Frequent washing of the hands, especially after using the bathroom or after touching the area of the sores is a good habit.

  • The above four herbs all have one thing in common, they enter the Gallbladder or Liver channels. They’re cool and drying. Cool and dry properties entering the Gallbladder and Liver channels is exactly what we want to treat “damp-heat”. Cool and dry is the opposite of hot and damp, get it?

Dang Gui 當歸 tangkuei, Chinese angelica root Radix Angelicae Sinensis [supports pregnancy]

Sheng Di Huang 生地黃 Chinese foxglove root, rehmannia (fresh),Rehmannia root Radix Rehmanniae Glutinosae

  • These two herbs both nourish the blood. The major function of this formula is to cool and dry. These two herbs prevent too much drying as they both nourish the healthy appropriate moistening elements of the body. Sheng Di also cools the blood, which might be indicated for those with red dots on the tongue such as the tongue picture on this page.

  • One method by which both damp and heat are removed from the body is through the urinary track. These three ingredients are all diuretics that are cool or cooling in nature.

  • As it is commonly used, this very sweet herb helps soften the harsh effects of the bitter cold drying herbs in this formula to protect the stomach and prevent side-effects of tummy ache for instance.



Modifications for Nocturnal Emissions (Wet Dreams) or Premature Ejaculation

This formula has a cooling effect on the “liver”. When the liver is cool, the temper is calmed. However while we’re cooling the emotions, we’re also cooling off other body functions including some reproductive activities. Heat that rises to the heart can induce intense dreams or over-the-top emotions. This can also cause nocturnal emissions or premature ejaculation. Cooling the liver is the first step in this process. The second is to use certain herbs that astringe the ejaculate such that it comes out less easily. These herbs are available as a separate formula to address the symptoms only, or as an add-on component to this formula.

The separate formula that includes these herbs for nocturnal emissions or premature ejaculation is called Metal Lock Pill to Stabilize the Essence (Jin Suo Gu Jing Tang)

Adding a bit to this formula addresses both the root-cause of this condition as well as the branch-symptoms. “Root and branch” are often treated together to address the both symptoms as well as regulate the underlying root disharmony giving rise to wet dreams or premature ejaculation.

Adult Dosage
  • I would suggest capsules for this.
  • Long Dan Xie Gan Tang should not be taken for more than a week to 10 days at a time.
  • start slow with 1 or two capsules or spoons- take with food or juice. This herb (until you get used to it) tastes Nasty. Bitterness drains heat and this formula is all about bitter. When it tastes good then you know it is working.
  • Be aware if it upsets your stomach and/or causes diarrhea. Cut back or stop then.

    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
