Native to India, holy basil is a medicinal herb traditionally used as a general health treatment for respiratory problems, headaches, stomach discomfort and fevers. Also known as tulsi, this Ayurvedic medicine may also be beneficial for people with Type 2 diabetes and asthma. Despite these benefits, the safety of using holy basil tea or other holy basil supplements during pregnancy is unknown.
Overall Safety
Researchers have not examined the safety of holy basil tea during pregnancy and lactation. In addition, health professionals with the University of Michigan Health System explain that large amounts of holy basil may make it difficult for a woman to become pregnant. For these reasons, avoid using holy basil tea during pregnancy without first consulting a doctor.
Adverse Effects
If your physician recommends treatment with holy basil tea, only take this medicinal herb as directed. The long-term safety of using holy basil for more than four weeks is not known. Generally, holy basil tea is not known to cause side effects when used as directed.
Drug Interactions
In addition to potential adverse effects, drug interactions may occur in people taking certain medications. Avoid using holy basil if you're taking an anticoagulant medication, such as heparin, warfarin or aspirin. Combining these treatments may increase your likelihood of developing bruising or bleeding. In addition, holy basil seed oil may cause severe drowsiness when combined with pentobarbital.
Contraindications
Women who are pregnant aren't the only people who should avoid drinking holy basil tea. Do not consume this medicinal tea if you're scheduled to have surgery within the coming two weeks. This herbal tea may increase your risk of bleeding during surgery.
