camphor oil

Camphor oil is an essential oil distilled from the wood of the camphor tree (*Cinnamomum camphora*) and contains camphor as its primary active component[6]. It is used topically as an antipruritic (to relieve itching), analgesic (to relieve pain), anti-infective, and anti-inflammatory agent[1][4][6]. Camphor oil is also employed for its decongestant effects (in vapor rubs for chest congestion and cough), antispasmodic properties for muscle cramps, and as an antifungal and antibacterial agent[2][3][6][8]. Its mechanism of action involves stimulation of sensory nerve endings, producing a cooling, warming, and numbing effect that leads to symptom relief[8]. Camphor oil is widely used in aromatherapy, personal care, natural home cleaning, and as a natural insect repellent[6]. Only the "white" grade of camphor oil is considered safe for medicinal and aromatic use; the FDA has banned concentrated camphorated oils due to toxicity risks, setting a topical maximum of 11% camphor in products[5][6].
