Ashwagandha: Nature’s Ancient Remedy Backed by Modern Science
In a world of ever-expanding wellness trends, Ashwagandha stands out—not as a fleeting fad, but as a time-tested herb with growing scientific support. Rooted in Ayurvedic medicine for over 3,000 years, Ashwagandha (Withania somnifera) has gained popularity for its potential to reduce stress, enhance energy levels, and support overall well-being. But how exactly does it work in the body? Is it better taken as a supplement or through diet? Let’s break down what the research says and how to make it work for you.
What Is Ashwagandha?
Ashwagandha, sometimes referred to as “Indian ginseng” or “winter cherry,” is a small shrub native to India and parts of the Middle East. The roots and leaves of the plant are used for medicinal purposes, and it is classified as an adaptogen—a natural substance believed to help the body adapt to stress.
How Ashwagandha Affects the Body
The active compounds in Ashwagandha include withanolides, alkaloids, and saponins, which are responsible for its therapeutic effects. Here’s how Ashwagandha impacts the body:
- Reduces Stress & Anxiety: Ashwagandha helps regulate cortisol, the body’s primary stress hormone. A 2019 randomized, double-blind, placebo-controlled study published in Medicine (Baltimore) found that 240 mg of ashwagandha extract significantly reduced perceived stress levels and serum cortisol after 60 days of use.
- Improves Sleep Quality: It has been shown to help improve sleep onset and quality. A study published in Cureus (2020) found that adults taking 300 mg of Ashwagandha extract twice daily reported significant improvements in sleep efficiency and total sleep time.
- Enhances Physical Performance: Ashwagandha may increase strength, muscle mass, and VO2 max. In a 2015 study published in the Journal of the International Society of Sports Nutrition, participants who took 600 mg of Ashwagandha daily for eight weeks had significantly greater gains in muscle strength and size compared to the placebo group.
- Supports Cognitive Health: Some evidence suggests Ashwagandha improves memory, attention, and cognitive function. A study in Journal of Dietary Supplements (2017) found improvements in memory and executive function in adults who took Ashwagandha root extract.
- May Support Thyroid and Immune Function: Ashwagandha may help balance thyroid hormones and enhance immune response, though more research is needed to confirm these benefits.
How the Body Uses Ashwagandha
Once ingested, Ashwagandha’s bioactive compounds, particularly withanolides, are absorbed in the gastrointestinal tract and exert their effects via the endocrine, nervous, and immune systems. These compounds influence neurotransmitter pathways like GABA (gamma-aminobutyric acid), which explains its calming effects. They also help regulate inflammatory markers like TNF-alpha and IL-6, which play a role in stress-related health conditions.
Supplements vs. Diet
Ashwagandha isn’t commonly found in everyday diets and is typically consumed as a supplement in forms like:
- Capsules or tablets
- Powders (often mixed with milk or smoothies)
- Liquid extracts or tinctures
Most clinical studies use standardized extracts—usually delivering 300–600 mg of withanolide-rich extract per day. This is significantly more concentrated than what you’d get from raw root powder, making supplements the preferred route for therapeutic benefits.
While some traditional dishes and teas may include Ashwagandha root powder, it’s challenging to achieve clinical dosages this way without consuming large quantities.
Pros and Cons of Ashwagandha
Pros:
- Natural adaptogen with centuries of traditional use
- Backed by clinical studies for stress, sleep, and performance
- Generally well-tolerated with minimal side effects
- Available in multiple forms and dosages
Cons:
- May interact with medications (e.g., thyroid meds, sedatives, immunosuppressants)
- Not recommended during pregnancy or for people with autoimmune diseases without medical supervision
- Quality can vary between supplement brands—standardization is key
- Some users report mild side effects like digestive upset or drowsiness
Summary
Ashwagandha bridges ancient wisdom and modern science as a promising adaptogenic herb. From reducing stress and anxiety to boosting physical and cognitive performance, its benefits are supported by a growing body of clinical evidence. The body uses Ashwagandha primarily through its active compounds, which influence hormonal and neurological pathways. While dietary incorporation is possible, supplementation is typically necessary to achieve therapeutic effects. As with any supplement, it’s wise to consult with a healthcare provider—especially if you’re managing other conditions or medication.
For some, it can be a powerful ally in the pursuit of holistic health and resilience.
