• Salicylic acid is a colorless crystalline organic acid which is widely used in organic synthesis and functions as a plant hormone. It is derived from the metabolism of salicin. In addition to being a compound that is chemically similar to but not identical to the active component of aspirin (acetylsalicylic acid) , it is probably best known for its use in anti-acne treatments. It is poorly soluble in water (0.2 g/100 ml H2O at 20°C) . [1]
• Salicylic acid (SA) is a phenolic phytohormone and is found in plants with roles in plant growth and development, photosynthesis, transpiration, ion uptake and transport. SA also induces specific changes in leaf anatomy and chloroplast structure. SA is involved in endogenous signaling, mediating in plant defense against pathogens. [2] It plays a role in the resistance to pathogens by inducing the production of 'pathogenesis-related proteins'. [citation needed] It is involved in the systemic acquired resistance [SAR] in which a pathogenic attack on older leaves causes the development of resistance in younger leaves, though whether SA is the transmitted signal is debatable.

Production:
Salicylic acid is an organic acid biosynthesized from the amino acid phenylalanine.

Sodium salicylate is commercially prepared by treating sodium phenolate (the sodium salt of phenol) with carbon dioxide at high pressure (100 atm) and high temperature (390K) - a method known as the Kolbe-Schmitt reaction. Acidification of the product with sulfuric acid gives salicylic acid:

It can be prepared by the hydrolysis of Aspirin (acetylsalicylic acid) [3] or methyl salicylate (Oil of Wintergreen) with a strong acid or base
