Please note that you should never self-prescribe TCM ingredients. A TCM ingredient is almost never eaten on its own but as part of a formula containing several ingredients that act together. Please consult a professional TCM practitionner, they will be best able to guide you.

Common TCM formulas in which snake gourds are used*:
In Traditional Chinese Medicine (TCM), snake gourds are plants that belong to the 'Cool herbs that transform Phlegm and stop Cough' category. In TCM Phlegm is a condition of Stagnation of Fluids which tends to start in the Spleen and then goes to the Lungs. If this overly accumulates it thickens and becomes pathological Phlegm. Phlegm, being a form of Stagnation, often starts as being Cool and transforms to Hot as the condition progresses. The herbs in this category are Cold in nature so they treat the later stages of the Stagnation: Hot and Dry-Phlegm with symptoms such as cough, goiter or scrofula.
As suggested by its category snake gourds are plants that are Cold in nature. This means that snake gourds typically help people who have too much "heat" in their body. Balance between Yin and Yang is a key health concept in TCM. Those who have too much heat in their body are said to either have a Yang excess (because Yang is Hot in nature) or a Yin deficiency (Yin is Cold in Nature). Depending on your condition snake gourds can help restore a harmonious balance between Yin and Yang.
Snake gourds also taste Sweet. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Sweet ingredients like snake gourds tend to slow down acute reactions and detoxify the body. They also have a tonic effect because they replenish Qi and Blood.
The tastes of ingredients in TCM also determine what organs and meridians they target. As such snake gourds are thought to target the Stomach, the Large intestine and the Lung. In TCM the Stomach is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine. The Large Intestine on the other hand receives the "impure" parts of the digested food from the Small Intestine, absorbs the remaining fluids and excrete the remainder as feces. In addition to performing respiration, the Lungs are thought to be a key part of the production chain for Qi and the body fluids that nourish the body.
An anti-human immunodeficiency virus (anti-HIV) protein capable of inhibiting HIV-1 infection and replication has been isolated and purified to homogeneity from Trichosanthes kirilowii. This protein, TAP 29 has a therapeutic index at least two orders of magnitude higher than that of trichosanthin. Thus TAP 29 may offer a broader safe dose range in the treatment of AIDS.1
