What is Siddha?

Siddha medicine is the most ancient medical system in southern India, and it provides effective natural remedies with minimal adverse events and affordability. The word Siddha denotes established truth. The people who established the Siddha school of thought were known as Siddhars. They documented their spiritualist findings in medicine and yoga in Tamil. Over the past few decades, there has been a global movement towards adopting Siddha as a supplemental or alternative medicine, recognising natural components as possible sources of novel pharmaceuticals.
