| Use and description |
Salicylic acid is not easily soluble in water, but is easily soluble in organic solvents such as ethanol, ether, propanol, and turpentine. It exists in willow bark, white pearl leaves, and sweet birch in nature, and is the "anti-inflammatory drug" of plants.
Humans have long discovered the medicinal properties of willow plant extracts (natural salicylic acid). Ancient Sumerian clay tablets have records of using willow leaves to treat arthritis. The oldest medical text in ancient Egypt, the Ebers Papyrus, records that the pain-relieving properties of dried willow leaves were known to the Egyptians at least more than 2,000 BC. The ancient Greek physician Hippocrates documented the medicinal properties of willow bark in the 5th century BC. This knowledge was repeatedly quoted by famous Greek and Roman physicians such as Galen. |
