Historical and Traditional Uses
Ayurvedic Roots
In Ayurveda, ashwagandha is classified as a rasayana, a type of herb believed to promote longevity, detoxification, and rejuvenation. Traditional uses of ashwagandha include treating stress, anxiety, fatigue, inflammation, and promoting healthy sleep patterns, brain function, and immunity. Its adaptogenic properties help the body adapt to stress, making it an ideal herb for general wellness support.
Traditional Applications
Ashwagandha has been used for centuries to treat a variety of ailments. In ancient texts, it is often referred to as a rejuvenator and a tonic for overall health. The herb is believed to balance the body’s systems, enhance vitality, and improve mental clarity. It is also used to support reproductive health and boost energy levels.
Cultural Significance
In many cultures, ashwagandha is considered a sacred plant. It is often used in rituals and traditional medicine practices. The herb’s name, which means “smell of the horse”, signifies its ability to impart the strength and vitality of a horse to those who consume it.
Modern Scientific Evidence
Stress and Anxiety Reduction
One of the most well-documented benefits of ashwagandha is its ability to reduce stress and anxiety. A 2021 systematic review published in the Journal of Herbal Medicine analyzed seven studies involving nearly 500 adults in India. The review found that participants who used ashwagandha for six to eight weeks experienced significant reductions in stress, anxiety, and cortisol levels, along with improved sleep and reduced fatigue compared to those who did not take the herb.
A 2022 clinical trial in Florida with 60 participants also reported positive changes in anxiety, stress, food cravings, and depression after 30 days of ashwagandha supplementation.
Cognitive Function and Mood
Recent research has also highlighted ashwagandha’s potential in improving cognitive function and mood. A study published in Nutrients in 2024 found that acute and repeated supplementation of ashwagandha improved markers of cognitive function and mood in participants.
Physical Performance and Muscle Strength
Ashwagandha is also used to enhance physical performance and muscle strength. The herb is believed to help muscles heal swifter and improve male reproductive health. It is commonly used by athletes to build endurance and strength.
Metabolic Health
Ashwagandha has shown promise in supporting metabolic health. Small studies suggest that the herb may enhance insulin sensitivity, facilitating glucose uptake by cells and potentially lowering blood sugar levels. This property could be particularly beneficial for individuals managing or at risk of type 2 diabetes.
Immune System Support
The herb has been shown to improve the immune profile of both the innate and adaptive immune systems. This makes it a valuable supplement for enhancing overall immune function.
Safety and Side Effects

Studies have shown that doses ranging from 600 mg/day to 1,250 mg/day are well-tolerated without significant side effects. However, some individuals may experience gastrointestinal issues such as stomach irritation, diarrhea, and, in rare cases, vomiting and nausea.
