Ashwagandha – Withania Somnifera
This lovely herb has seen a surge in popularity in recent years, so I thought it would be a good herb to start my herb info series. This herb is a member of the nightshade family and is native to India, north Africa and the middle east. It is sometimes called Indian Ginseng or Winter Cherry. Ashwagandha is what is known as an adaptogen. This means it works through endocrine system to modulate the effects of stress and increase resistance to physiological imbalances and disease by strengthening immune system, reducing inflammation, balancing hormones and acting as an anti-anxiety and anti-depressant.
Form:
The roots and leaves are the parts of the plant that are used. It can be found as a powder or capsule as well as cut/sifted root and leaf. Powdered form can be added to any food or drink and the cut/sifted form can be used to make a tea or tincture.
Dosage:
Note – it may take two weeks or longer to notice the benefits and long term use has not been studied, but many people do well with taking it long term.
• Standard dosage ranges from 300-600 mg of root extract daily usually divided between two doses. Clinical studies show safety up to 1250 mg daily.

Warnings/Contraindications
This herb has an extensive history of use and is generally believed to be safe. I take it myself and have for months and had no side effects, but that’s not to say that someone else won’t. But there are some things to consider when looking at the whole person. We do not know how ashwagandha affects a developing fetus, so as with all things when pregnant or planning to be you should ask your Dr. Since this herb stimulates the immune system it can worsen symptoms of autoimmune disorders. It also balances blood glucose levels so diabetics should also talk to a Dr. before using it. And as we don’t really know of any interactions, it is advisable to stop taking ashwagandha two weeks before any surgery.
Possible minimal side effects can include stomach upset, diarrhea, drowsiness, mild headache or skin rash. Some more concerning but also rarer side effects can include decreased apetite, dizziness, irregular heartbeat, liver problems, allergic reactions or breathing difficulties. And of course, if you have problems with any plants from the nightshade family (tomatoes, potatoes, eggplant, peppers, goji berries, etc), you probably should not take this herb.
Most of the contraindications for this herb are to avoid over-medicating for certain conditions and are as follows:
• Diabetes medication (insulin, metformin) – may dangerously lower blood sugar levels
• Blood pressure meds – can cause excessive drop in blood pressure and cause dizziness
• Sedatives and sleep meds – may increase drowsiness and impair mental alertness
• Anti-seizure meds – may interfere with seizure control and medication effectiveness
• Thyroid hormone replacement – can alter thyroid hormone levels and treatment balance
• Valerian root – sedative, Kava Kava – higher risk of liver toxicity, Ginseng – may cause overstimulation
