Now we move on the next of the more simple chemical families; sesquiterpenes, this family also has just hydrogen and carbon bonds about 15 of them. Due to this family being heavier chemically than monoterpenes the shelf life on these oils is also extended to around 6 years. Of course always remember these shelf lives are just approximations- how you store your oils will determine how long they last. 

Here are four of the chemical components within the Sesquiterpene family and their known therapeutic benefits:

Alpha Caryophyllene- anti-inflammatory and antitumoral

Beta Caryophyllene- anti-inflammatory, analgesic, antitumoral, antispasmodic and antiviral

Curcumene- anti-inflammatory and antitumoral
