Salicylates.

Salicylates, what are they, and why do people develop an intolerance to them?
Salicylates are an important plant hormone that are used to protect themselves from disease. They are derived from salicyclic acid. . Big pharma got their hands on it and used it as a prodrug to develop aspirin.
The liver uses glycine to detoxify it and clear it out but sometimes it builds up causing the body to develop an intolerance. Symptoms can be broad and significant, such as stomach pain, itchy skin, hives, headaches and swelling in the hands and feet. Salicylates have an ototoxic (toxic to the ear) effect which can initiate tinnitus. It can also cause metabolic acidosis and respiratory acidosis.
