Depending on your condition and what the pharmaceutical you are taking, do some researchers into how they developed that drug. The majority of the time, there was a source herb, plant, extract from a traditional medicine that was analyzed and synthesized by pharma. Typically, the synthesis is incomplete with them missing inactive ingredients of the natural medicine that augment/mitigate/balance the active ingredients to perform better than the synthesized version. The only significant advantage to lab created medicines is the precision of dosing. Other than that, it doesn't have much going for it.
