For those versed in Ayurveda and herbology, I imagine Ashwagandha would make it on the short list of herbs to take if stranded on a desert island. This warm and nourishing herb has a powerful tonifying effect and is a panacea for Vata disorders. Ashwagandha is a nervine tonic and nervine sedative, a muscle tonic, a respiratory tonic, boosts male libido, and is considered adaptogenic–meaning it helps us resist stress. It is warm and slightly oily, hence its value in balancing Vata. (Vata is aggravated by anything light, dry, cold, and mobile…think salad and air travel in the winter). If you suffer from weakness, anxiety, burnout, or a sleep disorder, Ashwagandha may be a good herb for you. You can take it in tincture form for a faster effect on the nervous system. If you are looking to build or repair tissue, take it in whole powdered form (you can mix it in hot water or warm milk or take as a capsule). Ashwagandha combines nicely with other tonic herbs such as Shatavari and Gotu Kola. If you have a lot of Pitta in your constitution, use caution because this herb does have a heating effect.
