Ashwagandha (Withania somnifera) benefits like stress and anxiety reduction have recently shot into the limelight, but its medicinal value goes way back to ancient India as Ayurvedic medicine. One of its traditional uses is as a poultice to manage swelling and boils.
When ground, the leaves have a characteristic ‘horse’ smell stemming from the word itself (Ashva meaning horse and Gandha meaning smell), a musky, earthy smell.
Ashwagandha description and constituents
Ashwagandha belongs to the family Solanaceae and is also called clustered winter cherry in some dialects. It is found natively in Africa, India, and some parts of southern Europe. The plant thrives in a well-drained, slightly alkaline soil mix and can be grown from divisions, cuttings, or propagation with seeds.
The leaves are longitudinally wrinkled, dull green, and with smooth edges and a velvety texture. The flowers appear bell-shaped and greenish yellow and are quite small, making them less visible on the plant. Ashwagandha has fruits that are round, red-orange berries enclosed in a thin, paper-like husk. The roots, being the most used parts, are long and tuberous with a brownish appearance on the outside but whitish on the inside.
Ashwagandha contains various chemicals like the alkaloids withanine, somniferine, tropine, hygrine, pseudotropin, steroid lactones, and isopelledrine. These compounds are tied to its biological activity.
Ashwagandha cultivation
Ashwagandha can be planted using seeds. Soak the seeds in water, usually overnight or around 12 hours, then plant them around half a centimeter deep. The seed will germinate in roughly 3 weeks. Plant in a well-drained soil of ph. 7-8, soil can be mixed with sand and compost in equal parts to improve drainage. The plant should be exposed to at least 6 hours of daily sunlight.
The plant matures after around 5 to 6 months. An indication of maturity is yellowing leaves and orange-red berries. Roots are dug up, thoroughly washed, dried, and stored in a cool, dry place for preservation. Ensure the plant has air circulation and dries thoroughly between watering, as too much water causes the stem to rot.
After harvesting, the roots are washed and then cut into pieces. The pieces are then dried in a warm, shaded area (but not direct sunlight to avoid the active constituents being denatured and losing their medicinal value). Once dry, the roots are ground into powder and stored away from moisture and sunlight.
