Kahweol is a diterpene molecule found in the beans of Coffea arabica. It is structurally related to cafestol.

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]
