TECA (Titrated Extract of Centella Asiatica)
Free genines (Asiatic acid & madecassic acid) 54%-66%
TECA, also called Selected Centella Triterpenes, is a highly purified extract, fractioned and enriched in triterpenic acid and triterpenic sugar ester fractions to reach about 40% of asiaticoside and about 60% of the triterpenic genins (asiatic acid and madecassic acid).
The purification steps are extreme and involve chemical treatments that remove the herbal matrix so that the final extract is a recombination of a highly refined extract with an isolated constituent and the natural proportion of the components is not maintained.
TECA biological activities show to be efficient in 3 main domains
Recommended dosage : 0.5%
