Adaptogenic effect of Bacopa monniera (Brahmi)

Area of Science:

• Pharmacology
• Phytochemistry
• Neuroscience

Background:

• Stress is a significant contributor to various diseases.
• Identifying effective plant-derived antistress agents (adaptogens) is crucial for health research.
• Bacopa monniera is explored for its potential adaptogenic properties.

Purpose of the Study:

• To evaluate the adaptogenic efficacy of a standardized Bacopa monniera extract.
• To compare its effects against acute stress (AS) and chronic stress (CS) models in rats.
• To use Panax root powder (Panax quinquefolium) as a reference standard.

Main Methods:

• Standardized Bacopa monniera extract and Panax root powder were administered to male SD rats.
• Rats were subjected to acute immobilization stress (150 min) or chronic immobilization stress (7 consecutive days).
• Biochemical parameters (plasma glucose, ALT, AST, CK, triglyceride, cholesterol), organ weights (adrenals, spleen, thymus), and ulcer scores were assessed.

Main Results:

• Acute stress increased ulcer index, adrenal weight, plasma glucose, ALT, AST, and CK. Bacopa monniera reversed these changes dose-dependently.
• Chronic stress increased ulcer index, adrenal weight, AST, and CK, while decreasing thymus and spleen weight, triglyceride, and cholesterol. Higher dose Bacopa monniera reversed these effects.
• Bacopa monniera demonstrated significant adaptogenic activity comparable to Panax root powder.

Conclusions:

• The standardized Bacopa monniera extract exhibits potent adaptogenic activity.
• Bacopa monniera effectively mitigates physiological and biochemical markers of both acute and chronic stress in rats.
• These findings support the use of Bacopa monniera as a natural antistress agent.
