Description
Camphor powder is a waxy, flammable, transparent solid with strong aroma.
Camphor is believed to be toxic to insects and is thus sometimes used as a repellent. Camphor is used as an alternative to mothballs. Camphor crystals are sometimes used to prevent damage to insect collections by other small insects. It is kept in clothes used on special occasions and festivals, and also in cupboard corners as a cockroach repellent. The smoke of camphor crystal or camphor incense sticks can be used as an environmentally-friendly mosquito repellent.
Camphor is commonly applied as a topical medication as a skin cream or ointment to relieve itching from insect bites, minor skin irritation, or joint pain.It is absorbed in the skin epidermis, where it stimulates nerve endings sensitive to heat and cold, producing a warm sensation when vigorously applied, or a cool sensation when applied gently. The action on nerve endings also induces a slight local analgesia.
Camphor is also used as an aerosol, typically by steam inhalation, to inhibit coughing and relieve upper airway congestion due to the common cold.
It is always incorporated into massage balm locally. It is mixed with petroleum jelly, mineral oil, waxes, methyl salicylate.
Recommended dosage: 0.2-1%
