Safety Notes
It is likely safe to take skullcap in small doses for a short time, but damage to the liver is possible. C1, C2 People with liver problems should not take skullcap. Not enough studies have been done to say whether it is safe to take for a long period. It is also not known whether it is safe to take by women who are pregnant or breastfeeding.
Interactions
Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse such as:
- People taking medicine for anxiety should talk to their doctor before taking skullcap. It may overwhelm the body.
- People taking blood thinners should talk to their doctor before taking skullcap. It may increase the risk of bleeding.
