salicylic acid
salicylic acid, also known as salicylic acid, salicylic acid, and o-hydroxybenzoic acid, is a fat-soluble organic acid that is widely found in nature and was originally extracted from willow bark. It is also found in the leaves of white pearl, sweet birch, cohote roots, tulip flowers, hibiscus hibiscus, maple and rabdosia leaves, mulberry fruit, the roots of Yunnan white pearl and other plants. It is also found in fruits, vegetables, nuts, herbs, jams, honey, yeast extracts, tea, coffee, juice, beer and wine. It has the chemical properties of phenl and acid. The reaction of dilute aqueous solution with feric trichloride can produce purple yellow iron complex, which decomposes in strong acid. In case of heavy metal ions such as mercuy, lead and silver, they form water-insoluble salts; It reacts with bromie water to form white precipitate of tribromophenl. Aqueous solution shows acidic reaction, can be neutralized by alkali or carbonate alkali to form sodium salt and soluble in water; When heated above the melting point, carboxylic acid is removed to form phenl

Medical field:
Antipyretic, analgesic, anti-rheumatic: salicylic acid has antipyretic, analgesic, anti-rheumatic effect, can be used to relieve fever, headache, joint pain, toothache, neuralgia and other symptoms caused by a variety of reasons.

Treatment of skin diseases:
Keratolytic: Different concentrations of salicylic acid preparations have different effects in the treatment of skin diseases. 2%-6% salicylic acid ointment can be used to treat superficial fungal skin diseases; About 10% salicylic acid cream, often used to treat acne, seborrheic dermatitis; Salicylic acid cream with a high concentration of more than 15% can be used to treat corny eyes, callus and some other wart-like lesions.
Antibacterial: Salicylic acid has an inhibitory or killing effect on some bacteria, which helps to treat skin problems caused by excessive bacterial reproduction, such as the treatment of fungal infectious skin diseases such as ringworm on the hands and feet.
