Camphor and Sandalwood

Camphor - Research
One clinical trial has been conducted in patients with various eye disorders using a multi-herb eye drop containing C. camphora.10  Studies have also been done testing camphor’s ability to repel and control various insects.11,12,13  
Camphor has been used by the Chinese for embalming, as an ingredient in soap,5  for wounds and skin diseases, and as a stimulant in unconsciousness.1  It has been applied externally as a folk remedy for gout, muscular strains, inflammations, itching skin, and as a weak antiseptic. In Mexico, camphor in olive oil is a popular topical remedy for bruises and pain.4  
Topically, camphor is used to relieve pain, specifically on cold sores, hemorrhoids, warts, minor burns, and as an eardrop.6  Camphor is found in over-the-counter backache medications and products that treat skin conditions such as acne and oily skin. It is also a component in products used to treat bronchitis, chills, colds, coughs, and fever. Camphor has been used to increase blood flow to the skin, and has mild anesthetic and anti-itching properties.7  It is used as a moth repellent and as a preservative in pharmaceuticals and cosmetics.7  Camphor oil is used in skin care, for muscle and joint aches and pains; and as an insect repellent.3  
Camphor is approved by the German Commission E for external use in the treatment of muscular rheumatism and inflammatory diseases of the respiratory tract.8  The U. S. Food and Drug Administration (FDA) has recognized camphor as safe and effective for topical use to relieve pain, cough, and itching.9
