Coleus forskohlii Identity & Plant Part
The botanical entity is Coleus forskohlii (Willd.) Briq., a member of the Lamiaceae also written as Plectranthus barbatus in many references. The part used is the root, which is swollen and tuberous, with a strong aromatic smell when cut. Leaves, stems and flowers are not part of this ingredient.
The identity point buyers meet most often is the forskolin figure. Forskolin is a labdane diterpene found in the root, and it is the compound that standardized Coleus products are defined by. Coleus root also carries essential oil, starch and polysaccharides, named only as constituent families. A ratio extract keeps these alongside the diterpene, and does not quantify any of them.
Coleus forskohlii roots are cleaned, sliced and dried before extraction, and the botanical name on the certificate is the safest check of what was used.
