Hello David, Does Herbalists and Alchemists offer testing services for the efficacy of herbs? We are looking at growing some things like Tulsi, Shatavari, Ashwagandha, Gotu Kola, Bacopa, Vitex, etc. and would be interested in testing the quality of the herbs. If H&A doesn't offer it, are there places you would recommend in the US for quality testing herbs? Thanks so much, Cathy

No, we are not a testing lab. What do you want to test ? Constituents, bacteria , heavy metals ?

I'm looking to test constituents and the quality of the medicine, primarily.

I don’t know any labs that test for quality per se, most test for bacterial, fungal, heavy metal contamination, You can only test an herb for marker compounds, or isolated chemical like berberine, which often have little relationship to quality. Quality can be determined via organoleptic testing (taste, color, odor, freshness, botanical ID, etc). You can also do HPLC’s which most labs do, but they are comparing your sample to samples they have run before and if the samples are not great quality , then your herb may not match.
