Interaction Details
There were no interactions found between Collagenase Clostridium Histolyticum-Aaes and Eurycoma Longifolia. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Pharmacist Analysis
Although there is no known interaction in this case, Eurycoma longifolia, most commonly known as Tongkat Ali, does have some potential interactions that are important to be aware of.
For example, it may interact with the following:
- CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES
- CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES
- CYTOCHROME P450 2A6 (CYP2A6) SUBSTRATES
- Propranolol
- Testosterone
Tongkat Ali has been reported to inhibit certain metabolizing enzymes in the liver (the ones mentioned above) and therefore, may increase the levels of substances metabolized by those enzymes. This could potentially affect the way these substances work or how long they stay in your system.
In regard to propranolol, some studies show that Tongkat Ali decreases how well propranolol is absorbed in the gut and could reduce its effects. It is not known if separating administration will prevent this interaction/
Lastly, testosterone, Tongkat Ali may theoretically further increase levels of testosterone, a hormone responsible for various functions in the body. You should be cautious combining the two.

Eurycoma longifolia, also known as tongkat ali or "Malaysian ginseng," is a plant native to Southeast Asia. It is a member of the Simaroubaceae family and is known for its small, yellow flowers and elongated, slender leaves.
It has a long history of use in traditional medicine and is thought to have anti-inflammatory and pain-relieving effects.
Eurycoma longifolia is also purported to have a number of other medicinal properties, including the ability to improve immune function, reduce the risk of heart disease, and lower cholesterol levels.
Additionally, Eurycoma longifolia is commonly used as a natural treatment for male infertility and as a natural performance-enhancing supplement as it may have a mild androgenic effect. When used for male enhancement, it is most often marketed under other common names for the plant (e.g., tongkat ali, longjack).
Collagenase Clostridium Histolyticum-Aaes Overview
-
Collagenase Clostridium histolyticum injection (Xiaflex) is used to treat Dupuytren's contracture (a painless thickening and tightening of tissue [cord] beneath the skin in the palm of the hand, which may make it difficult to straighten one or more fingers) when a cord of tissue can be felt upon examination. Collagenase Clostridium histolyticum injection (Xiaflex) is also used to treat Peyronie's disease (a thickening of tissue [plaque] inside the penis that causes the penis to curve). Collagenase Clostridium histolyticum injection (QWO) is also used to treat cellulite (fat deposit beneath the skin) in the buttocks of adult women. Collagenase Clostridium histolyticum injection is in a class of medications called enzymes. In people with Dupuytren's contracture, it works by helping to break down the cord of thickened tissue and allows the finger(s) to be straightened. In people with Peyronie's disease, it works by helping to break down the plaque of thickened tissue and allows the penis to be straightened. In women with cellulite, it works by releasing fibrous bands, redistributing fat cells, and stimulating the growth of new collagen.
