The Village Pharmacy Tree

Revered in rural India as "Arishta" (meaning "reliever of sickness"), the Neem Tree (Azadirachta indica) has provided oral hygiene twigs (Datun), purifying bath leaves, and natural skin remedies for millennia.

1. Tetranortriterpenoid Bioactives

Azadirachtin & Nimbin:

- Disrupts microbial cell membranes and inhibits the synthesis of extracellular glucans by Streptococcus mutans, preventing oral dental plaque adhesion.

Cutaneous Eczema & Blemish Relief:

- Topical diluted neem seed oil balances sebum production and calms redness without stripping the protective skin microbiome.
