Camphor

Christopher Hobbs:

“Camphor oil is used externally in moderate amounts for bronchitis, eczema, and as a steam inhalant for colds and lung congestion. It is a common ingredient in balms, ointments, and lotions. Camphor is also indicated for muscle pain, chills, fainting (use as a smelling salt), and sunstroke. Internally, camphor is used in Ayurveda, the ancient East Indian system of healing, and Traditional Chinese Medicine to strengthen and activate the nervous system and stimulate digestion. However, internal doses over 2 grams have caused convulsions, delirium, hallucinations, and death.

Camphor has a taste of SPICY, BITTER and a temperature of WARM.”

Historical Uses

Historically, camphor was widely used in Asia and the Middle East, often in incense, as an embalming agent, and for medicinal purposes like treating inflammation, pain, and respiratory issues. It was used in traditional Chinese and Ayurvedic medicine for its warming, stimulating, and antimicrobial properties.

Modern Clinical Uses

In modern herbalism and naturopathy, camphor remains valued as a topical treatment for pain, inflammation, itching, and respiratory congestion. It is commonly found in over-the-counter balms, liniments, and chest rubs for these purposes. Aromatherapy practitioners use it for its menthol-like scent, often to clear nasal passages and relieve congestion.

Chemistry

Chemically, camphor is a terpenoid ketone obtained from the camphor tree (Cinnamomum camphora) and synthesized from turpentine oil. It is a waxy, flammable solid with a strong odor. Structurally, it’s made up of a bicyclic monoterpene skeleton.

Pharmacology

Pharmacologically, camphor acts as a counterirritant, producing a cooling effect followed by warmth, which helps relieve pain by stimulating nerve endings. It has mild anesthetic and antimicrobial properties. When inhaled, it acts as a decongestant, and its vapor can open up airways, providing relief from nasal and respiratory blockages.

Clinical Trials

Limited clinical trials exist on camphor alone, though some studies support its efficacy in combination products for pain relief and respiratory issues. Small trials have shown benefits in muscle and joint pain when combined with menthol and other herbs, and some studies suggest potential benefits in wound healing, though more rigorous studies are needed.

Summary

Camphor is a historically important substance with well-established uses in topical pain relief and decongestion. Modern science supports some traditional claims, though care must be taken to avoid toxicity, especially with ingestion. Clinical research is ongoing, though current evidence supports its efficacy primarily in topical applications.
