Herbs to Avoid When Pregnant

Herbs to Avoid When Pregnant

Posted by THT Katie on 31st May 2021

This is not a complete list of herbs to avoid during pregnancy or breastfeeding, but rather a list of commonly used herbs found in foods, herbal preparations, and supplements.  Some herbs are considered to be generally toxic and should not be ingested, while others are considered generally safe, with the possibility of decreasing breastmilk supply in lactating women. 

While this list is a valuable reference, it is always best to check with your healthcare practitioner before taking therapeutic amounts of any herb while pregnant or breastfeeding.
