Kahweol is a diterpenoid molecule found in the beans of Coffea arabica. It is structurally related to cafestol. It gets its name from the Arabic word "Ka-ah-wa", from which "coffee" derives. In French, it's evolved into the slang word "kawa", to designate coffee.

Recent research suggests that kahweol may have beneficial effects on bone by inhibiting osteoclast differentiation.[1] Another recent study confirmed that kahweol has anti-inflammatory and anti-angiogenic effects, offering a possible mechanism for the association found in epidemiological studies between consumption of unfiltered coffee and decreased risk of cancer.[2]
