Just for good health then?
Here's the article I read about it:
The majority of the medicinal and psychoactive potential of the cannabis plant lives in the cola, covering
calyxes with crystally resin. Yet, fan leaves do contain some of the vital cannabinoids and acids that give the plant therapeutic value. However, fan leaves only contain trace amounts of these compounds.
In 1971, the
United Nations report comparing cannabinoid levels in
male and female plants found that the large leaves of some specimens contained as much as 0.3% THC and 0.7% CBD. These results were from a limited number of samples from 8 different geographical regions.
However, a couple of the samples tested negative for detectable amounts of THC. Samples taken from the upper leaves of cannabis plants tested higher for CBD/THC.
Fan leaves can also be dried and used in teas. The psychoactive effect of drinking cannabis tea is debatable. The resin of the cannabis plant is what holds cannabinoids, but the resin is fat soluble. For the cannabinoids to produce psychotropic changes, the resin needs to be dissolved into a fat.
Simply adding dried cannabis leaves into a hot water for an herbal tea may promote relaxation, but it is unlikely to cause an out-of-this-world experience. Heating dried fan leaves in some
coconut oil will extract and amplify whatever cannabinoids happen to be present in the leaves.
Similar to teas, dried cannabis fan leaves can be infused into coconut oil (or any other kind of fat) to be used in topical skin creams and balms. The small amount of resin and other nutrients in the leaves work well for surface application, which does not cause psychoactive effects.
