Reported Mechanism (Provisional)

Mechanism of Action

Neem's primary compounds nimbidin, nimbin, and azadirachtin inhibit NF-κB inflammatory pathways while stimulating macrophage activation. Limonoids in neem disrupt bacterial cell wall synthesis and interfere with fungal ergosterol production. The compounds also modulate cytokine production, reducing pro-inflammatory IL-6 and TNF-α while supporting beneficial immune responses.

Clinical Narrative (Provisional)

Human studies on neem leaf are limited, with most evidence from small trials of 20-60 participants using 500-1000mg daily doses. A 12-week study showed 23% reduction in acne lesions compared to placebo, while another trial demonstrated 18% increase in white blood cell count. Most research consists of in-vitro and animal studies showing antimicrobial and immunomodulatory effects. Clinical evidence remains preliminary and requires larger, longer-duration trials for definitive health claims.
