Synergistic anticonvulsant activity of oregano, chamomile, and lavender via intranasal administration: A dose-response modeling approach.

BACKGROUND

This short communication presents an analytical approach to evaluate the synergistic anticonvulsant effects of an herbal combination containing hydroalcoholic extracts of Origanum vulgare (oregano), Matricaria chamomilla (chamomile), and Lavandula angustifolia (lavender).

OBJECTIVE

The study aimed to apply linear dose-response modeling to seizure score data to predict the expected outcomes of combination therapy and quantify synergy by comparing predicted and observed effects.

METHODS

The herbal extracts were obtained through maceration with 70% ethanol. The animal study was performed using 2 different doses of each herb, involving 36 rats in 6 groups. Building on previous in vivo findings, the study utilized linear dose-response modeling to analyze the effects of the combination therapy on seizure scores and to determine the synergistic performance at combination doses of 17mg/kg, 34mg/kg, and 68mg/kg.

RESULTS

The results highlighted the synergistic performance of the herbal combination, particularly at the dose of 34mg/kg, demonstrating the pharmacodynamic advantages of combination therapy and confirming the enhanced antiseizure effect of the herbal combination.

CONCLUSIONS

This study confirms the synergistic anticonvulsant effects of the herbal combination and demonstrates its potential as a new supplementary treatment for seizures via a non-invasive intranasal administration method.
