Ashwagandha Materia Medica

Ashwagandha Materia Medica

  “I’m so stressed!!!”  If you have said these words to yourself in the past two weeks, you need ashwagandha.  “I’m so tired,” “I can’t take this anymore,” “I need a nap,” and “point me to the nearest bar,” all count too.  Because all of us, at one time or another, balance plates on our heads while juggling sharp swords, it can easily be said that ashwagandha is a plant that everyone needs. Its wide-ranging capabilities and pleasant taste make it a wonder herb, and while the plates and swords are a metaphor, this herb’s anxiety-reducing capabilities are not...

Appears to have both immunosuppressive and immune tonic qualities, bringing a depleted, overly stimulated or stressed body back into balance. (pg 133, Pole, Adaptogens, pg 140)
  • Donald Yance recommends using ashwagandha during and after radiation therapy as he says it ³significantly increases white blood cell count, reducing leucopenia caused by radiation and immune suppressive drugs.².(Pg 127, Herbal Medicine, Healing and Cancer)

  • Thyroid: Useful in hypothyroid disorders. Enhances endocrine function
  Preparation and Dosage
  • Powder: 1/2-1 tsp powder in 4-8 oz of warm milk (dairy, coconut milk, almond milk, oat milk…) with honey, once or twice per day. Mix the powder into honey or ghee if you do not drink milk. Ayurvedic practitioners recommend using ashwagandha powder in a ³reproductive tissue building carrier²; milk, ghee, almond milk and honey.
  • Ashwagandha powder can be mixed in a 50/50 ratio with organic ghee and taken in teaspoon doses, 2-3 times per day.
  • Tincture (1:3 or 1:5): made from dried roots, take 1/4-1 teaspoon, 3 times per day.
  • Capsules: 400-500 mg, twice a day.
  Safety considerations:
  • Not recommended during acute infections, or for a person with severe congestion or high ama (thick coated tongue, chronic constipation). Because of the roots warming qualities it may be too heating for people who run hot. May potentiate the action of barbiturates. (Adaptogens, p. 141)
  • Traditionally used in India in small amounts, less than 3 grams/day, during pregnancy to calm a restless fetus and strengthen the mother. Pg 39, Herbal Therapy and Supplements
  • In the west it’s use during pregnancy is not recommended because of possible spasmolytic activity to the uterus. Best to consult with your midwife and Ayurvedic practitioner if pregnant. ³
  • The evidence contradicting its use during pregnancy is limited and questionable, and Ayurvedic practitioners have used it traditionally during pregnancy² writes Aviva Romm, pg 202, from her book Botanical Medicine For Women¹s Health.
  • Avoid using if you have an allergy or sensitivity to plants in the nightshade family (ie: tomatoes, potatoes, eggplant). Consult your healthcare practitioner if you have hyperthyroidism before using ashwagandha as it stimulates the thyroid.
Long-term safety: No safety issues expected.
