Camphor is a colorless or white crystal, granular or fragile. It has an irritating aroma.Chemical Abstracts Agency nimber is 76-22-2, formula is C10H1O6, shiny, hot and toxic. For the center,the spleen has a dispersive analgesic effect, dehumidifies and kill insects, treat itching, pain and toothache. The camphor tree is extracted from the branches and steams, leaves roots and granular crystals of the camphor family plants. Camphor has the effects of through-hole, stagnation of qi, opening,dehumidify, insecticidal and antipruitic and analgestic, and treatment of itching, trauma, scabies and other toothache symptoms. The main ingredients is pure camphor,which is a camphor compound. Function The main function of camphor is: kill insects and stop itching, detumescence and pain, clear the orifes, benefit stagnant qi, and remove the filth. It is often used in solid wood furniture or wardrobe to prevent mildew and kill insects. Application 1. The role of the central nervous system Camphor have excited central nervous system 2. The effects on the cardiovascular system 3. The local action Camphor spread on the skin has a mild stimulation and corrosion protection. Hard hair red inunction. 4. The antifungal effect In vitro experiment of wool sample microspore bacteria, red hair versicolor bacterium has a strong inhibitory effect, can completely inhibit its growth in the plate 5: Insect repellants
