How were the formulas developed?

The formulas, that now form the basis of Tri Health's Ayurvedic oils and supplements, were called ‘yogas’, in this case 'yoga' means the ‘union of the herbs’.

The formulas were developed by the Ashtavaidyas in three ways:

• Through the merging of several streams of knowledge across families leading to unique 'Ashtavaidya' formulas.
• Through improvised versions of the recipes from the ancient Ayurvedic texts.  Through their inherited wisdom, they came to understand exactly how to add a certain herb to a classical formula as certain herbs became extinct or difficult to obtain.
• Through classical formulas from texts indigenous to Kerala.
