What Are Adaptogens?
Adaptogens are a unique class of herbs that help the body "adapt" to physical, chemical, and biological stressors. The term was coined in 1947 by Soviet pharmacologist Dr. Nikolai Lazarev, who defined an adaptogen as a substance that:
- Produces a non-specific resistance to multiple stressors
- Has a normalizing effect on body functions
- Is safe and non-toxic when used as directed
Think of adaptogens as a thermostat for your stress response. They don't just stimulate or sedate — they help your body find balance, upregulating systems that are low and downregulating those that are overactive.
How Do Adaptogens Work?
Adaptogens work primarily through the hypothalamic-pituitary-adrenal (HPA) axis, which is the central stress response system in your body. They modulate cortisol levels, improve stress resilience, and support adrenal function.
Key mechanisms include:
- Modulating cortisol and stress hormone production
- Supporting adrenal gland health and function
- Enhancing mitochondrial function and cellular energy
- Reducing oxidative stress and inflammation
- Supporting neuroendocrine balance
