When your average pharmaceutical product gets into the headlines because of side effects, then it’s almost always because of some unwanted effects that have been discovered “later on”.
With tongkat ali, it’s a different story. The more research is done into tongkat ali, the more surprising positive side effects, or medical applications, are discovered for it. Not that this would be news to Southeast Asian shamans who have been using the root for centuries. In Vietnam, for example, the local name of tongkat ali translates as “the plant that cures a hundred diseases”. Or was it a thousand?
The latest lab reports indicate, for example, that tongkat ali (Eurycoma longifolia by its Latin, scientific name) may be a powerful weapon against lung cancer and breast cancer.
