I am not so sure this is the case. The root of the plant Coleus Forskohlii contains the diterpene forskolin, as well as other coleonols/diterpenoids/volatile oils. Some of these (and other) plant constituents support forskolin's pharmacological activity and absorption, although practically all of the pharmacological properties of the plant, coleus forskohlii, are traced to forskolin. So, although some volatile oils in coleus may help forskolin pharmacology and absorption, exogenous fats are not necessarily required for forskolin absorption.
