Extracts of Boswellia serrata have been clinically studied for osteoarthritis and joint function, particularly for osteoarthritis of the knee. A Boswellia extract marketed under the name Wokvel has undergone human efficacy, comparative, pharmacokinetic studies. Boswellia serrata is used in the manufacture of the supposed anti-wrinkle agent "Boswelox", which has been criticised as being ineffective.
Boswellic acids are a series of pentacyclic triterpene molecules that are produced by plants in the genus Boswellia. Like many other terpenes, boswellic acids appear in the resin of the plant that exudes them; it is estimated that they make up 30% of the resin of frankincense. While frankincense powder boswellic acids are a major component of the resin its important to note that the steam or hydro distilled frankincense essential oil does not contain any boswellic acid as these components are non-volatile and too large to come over in the steam distillation process (the essential oil is composed mainly of the much lighter monoterpene and sesquiterpene molecules with small amounts of diterpenoid components being the upper limit in terms of molecular weight).
