Salicylic acid is a colorless, crystalline organic acid that melts at 159°C; it is soluble in alcohol but is only slightly soluble in water. Salicylic acid is an ingredient used in many over-the-counter acne medications.
Fruits and vegetables are natural sources of salicylic acid, with fruits having large amounts of salicylates, particularly berries. Some herbs and spices contain quite high amounts, and meat, poultry, fish, eggs and dairy products all have little to no salicylates. Of the legumes, seeds, nuts, and cereals, only almonds, water chestnuts and peanuts have significant amounts. The table below gives more examples of foods containing salicylates:
