In recent years, Ashwagandha ( Withania somnifera) has emerged as one of the most popular herbs in the natural products space. A member of the nightshade family, the dried and powdered roots have been used in Ayurvedic, Unani, and sub-Saharan African traditions for millennia as “rasayana” (rejuvenator) for a plethora of applications, including sleep difficulties, debility, reproductive health, skin and digestive conditions, joint pain, and immune support. Named after the Sanskrit words ashva (“horse”) and gandha (“smell”), ashwagandha root does impart a strong scent as well as the strength and vitality of the magnificent animal. Traditionally consumed as a fine powder mixed with water, milk, ghee, or honey, ashwagandha is generally considered safe for children, adults and elders alike with only a few specific exceptions (see “Dosage, Safety & Side Effects” below).
Ashwagandha Root Benefits
Popularized in recent years as an "adaptogen," ashwagandha certainly rises to the occasion. “Adaptogen” is a modern Western herbal term that emerged from Soviet research in the 1970s describing botanicals that promote resilience to stress, normalize physiologic functions in the body, and are safe to use long-term. Ancient tonic herbs such as Panax ginseng, eleuthero, and rhodiola were some of the first adaptogens to earn this appellation, and recent additions include ashwagandha, holy basil, licorice, and schisandra berry. These herbs are believed to act upon the hypothalamic-pituitary-adrenal axis to modulate cortisol production, facilitating a healthy stress response, blood sugar levels, and sleep-wake cycles.
ASHWAGANDHA FOR STRESS RELIEF & SLEEP
Ashwagandha makes such a wonderful adaptogen because it strikes a balance between relaxing and energizing. Many studies demonstrate the benefits of ashwagandha consumption for stress relief. While it does not cause drowsiness on its own, ashwagandha can be combined with soporific herbs like hops and valerian to help us sink into sleep. Rather than signaling the body to push through and override stress, ashwagandha supports our ability to relax and let go of worry so that we can get natural, recuperative rest and wake up refreshed. A warm cup of ashwagandha-infused “moon milk” before bed is a delicious and gentle way to ease into a good night’s sleep (keep reading for two tasty moon milk recipes!).
ASHWAGANDHA FOR ENERGY & STAMINA
Ashwagandha can also be taken during the day with energizing herbs like eleuthero and rhodiola (as in our Sustainable Energy adaptogen tincture) to promote focus, calm, and energy without the buzz of caffeine. Ashwagandha has historically been used for recovering from illness and promoting vitality, and modern research confirms its ability to improve physical endurance. A study of 50 healthy athletes demonstrated that ashwagandha improved athletic performance indicators such as oxygen-carrying capacity, muscle strength, and exercise endurance in those treated with doses up to 1250 mg per day. Whether you are running a marathon on the road, in the office, or as a caregiver, ashwagandha provides the support we all need to strive under mental, emotional, and physical stress.
ASHWAGANDHA FOR INFLAMMATION & THE IMMUNE SYSTEM
Another set of ancient applications of ashwagandha—alleviating painful joints, promoting resilience, and fighting germs—is being born out in contemporary research on the modulating effects of ashwagandha for the immune system. Increasingly, scientists are discovering that many chronic conditions, including autoimmune diseases, cardiovascular disease, degenerative neurological conditions, diabetes, and cancers result from persistent inflammatory states. While ashwagandha has not been proven to prevent or treat any of these diseases, in vitro and animal studies suggest that active constituents found in ashwagandha (such as withaferin) may tone-down inflammatory signal proteins and protect against oxidative stress. Ashwagandha has also been shown to promote red and white blood cell production. These same properties contribute to ashwagandha’s benefit in acute illnesses and in recuperating afterwards. Ashwagandha thus combines well with other powerhouse herbs like turmeric and ginger to soothe aches and support a healthy immune response.
ASHWAGANDHA FOR SEXUALITY
Traditionally known as a sexual tonic for men, ashwagandha has an equally beneficial influence on femenine sexuality. In addition to generally improving strength and endurance, the stress-relieving benefits of ashwagandha likely help us relax enough to enjoy sensuality—a state of mind and mood which can be difficult when we are worried and depleted. Stress can also impact men’s fertility, and studies suggest that ashwagandha may combat the impact of stress on sperm quality. So whether you are trying to conceive or just need some support in feeling more sexy, consider blending ashwagandha with other romance-enhancing herbs like damiana and epimedium.
Ashwagandha Dosage, Safety & Side Effects
Traditional doses of dry ashwagandha root powder range from 250 mg to 1000 mg daily, and studies have shown safety of these amounts when taken for up to 12 weeks. Major constituents in ashwagandha root include steroidal lactones (known as withanolides) and alkaloids. Some products are standardized to a percentage of withanolides. The exact mechanism of metabolism is not well known. Side effects are rare but may include GI upset or skin rash. Five case reports of liver injury were resolved by discontinuing use of the supplement and did not result in long-term damage.
Ashwagandha is considered safe for a wide range of individuals, but it may not be appropriate in some cases. In general, ashwagandha should be avoided by those who are pregnant. Due to its immune-enhancing effects, individuals taking immunosuppressant drugs like cyclophosphamide should avoid ashwagandha. Because ashwagandha may boost thyroid function, it should be used with caution in individuals with hyperthyroidism or those who take thyroid hormone replacement.
Because ashwagandha is relaxing, it could hypothetically interact with medications for sleep or anxiety, though this has not been demonstrated in any studies. It is also possible that ashwagandha might interact with medications that lower blood sugar and blood pressure.
Growing Ashwagandha Plants
Ashwagandha is related to tomatoes, though its red fruits are not edible. It needs a greenhouse to survive the winter months in cold climates, whereas it grows naturally year-round in its native tropical climate. It is easy to grow from seed—simply transplant two-month-old plants about one foot apart into deep, loamy soil where the roots can grow unhindered. Water consistently but not excessively, keeping the ground moist around each plant, and side dress with organic compost one to two times during the season if the plant is not growing vibrantly. Each plant will grow to approximately one foot wide by two feet tall. The roots can be harvested after approximately one year, or after the plant has gone to seed.
