Camphene is monoterpene which emits pungent odors of damp woodlands and fir needles. Camphene may play a critical role in cardiovascular disease. Clinical studies have found camphene reduces plasma cholesterol and triglycerides in hyperlipidemic rats. Given the importance that the control of hyperlipid- emia plays in heart disease, the results of this study provide insight into how camphene might be used as an alternative to pharma- ceutical lipid lowering agents which are proven to cause intestinal problems, liver damage and muscle inflammation. This finding alone warrants further investigation.
