Ashwagandha is an herb, which interestingly means “the smell of a horse” in Sanskrit.

It is said to hold the strength of a stallion, and has traditionally been prescribed in ancient Ayurveda to help people strengthen their immune systems

Ashwagandha can help with a variety of health goals, including:

Strengthening the immune system;  Reducing stress and anxiety;  Improving blood sugar and cholesterol levels;  Reducing inflammation;  Improving focus and cognitive function

How does it work?
In Ayurveda, there are specific herbs with adaptogenic actions, and Ashwagandha is one of them

Adaptogens are substances (a combination of amino acids, vitamins, and herbs) that modulate your response to stress or a changing environment

This is how they help your body cope with external stresses such as toxins in the environment and internal stresses such as anxiety and insomnia

It can be taken at any time of day in 500 – 1,000mg doses, although many people find it best in the morning or just before bed.
