IGHE and anaphylaxis: Sridevi et al. (2009) highlighted that the ethanolic extract of Ocimum sanctum at 400 mg/kg effectively reduced mortality (41%) due to anaphylactic shock-induced bronchospasm in tested subjects with a significant drop (P < 0.001) in serum IgE level to 25.80 ± 4.85 ng/ml (P < 0.001), as compared to sensitized control (125.06 ± 9.66 ng/ml). These findings confirm that the anti-allergic potential of O. sanctum is worthwhile to be further explored.
