Are there scientific studies that prove the medical effectiveness of Coleus forskohlii?

Yes, there are several scientific studies that prove the medicianl effectiveness of Coleus forskohlii. The following is an interesting one.

According to a study published by "Probiotics and antimicrobial proteins", the application of native bacterial endophyte CFRB1 (Alcaligenes faecalis) to Coleus forskohlii significantly enhanced its photosynthetic pigments and reduced the severity of root-knot and root rot diseases. Additionally, CFRB1 treatment led to a 81% reduction in nematode infection and a 78% reduction in root rot in Coleus forskohlii plants. Furthermore, this interaction between the plant and endophyte resulted in the upregulation of genes involved in the forskolin biosynthesis pathway, ultimately increasing the plant's forskolin content and yield.
