2 problems with the study : 384 patients is too few to draw a conclusion. Second problem - the study is authored by Api Chewcharat, a Thai national first year MD student. Clearly desperate to make a splash in the medical publishing world, from a country rife with corruption and unfamiliar with high ethical standards. For both of these reasons, take this with a huge grain of salt.
I think I should have addressed my #22 to you as well! ;)

Been using it for years, as have others I know. Works. Works quickly. Good for a gall stones, kidney stones and gout crystals.
No need for a study.
Most poorer countries have at least one local remedy that is sovereign for something major. Western pharm companies take those, isolate the effective ingredient, purify it, and sell it back for $$$$. Then they attempt to denigrate the original herb and if that is ineffective, they get governments to ban it.
