Ayurvedic Integration: Traditional Wisdom Meets Modern Science

Neem's role in Ayurveda provides a comprehensive framework for microbiome health:

Rasa (Taste): Bitter and astringent - balances excess kapha and pitta
Virya (Energy): Cooling - reduces inflammation and heat in the body
Vipaka (Post-digestive Effect): Pungent - supports digestion and elimination
Dosha Balance: Primarily reduces kapha and pitta, increases vata when imbalanced
Prabhava (Special Effect): Deep detoxification and immune enhancement

The Microbiome Balancing Advantage

Unlike broad-spectrum antimicrobials, neem provides intelligent microbial modulation:

Selective Targeting: Affects specific pathogens while preserving beneficial bacteria
Prebiotic Effects: Supports beneficial microbial growth through metabolic byproducts
