Holy basil, also called tulsi, is a herb traditionally used in Ayurvedic or alternative medicine. It may be able to treat certain physical and emotional health conditions when used alongside prescription medicine. If you want to take holy basil as a supplement, knowing how and why to ingest it can boost its therapeutic benefits while minimizing potential side effects. Luckily, a 2017 review of all available studies on holy basil indicates that there are minimal side effects and that holy basil may be an effective treatment for a variety of conditions.[1]

Trying Different Forms of Holy Basil

  1. 1
    Drink a cup of holy basil tea to treat mild conditions. Holy basil tea is great for relieving mild, occasional bouts of emotional stress or receiving its health benefits in low doses. Take a cup when you're feeling nervous or overwhelmed to receive relief within several hours.[11]
  2. 2
    Take holy basil capsules for their potency. Holy basil capsules or tablets are concentrated and offer a stronger dose than teas. Buy holy basil capsules online or at some health food stores, and take it with food or water to help your body absorb it quickly.
    • Because of their potency and relaxing supplements, holy basil capsules can be used as natural sleep supplements.[13]
    • Never take more than the package's recommended dosage at a time.
  3. 3
    Steep holy basil leaves to make a medicinal soup. Holy basil soup is an effective way to receive its health benefits if you dislike the taste of tea. Holy basil pairs particularly well with shiitake, maitake, and reishi mushrooms or astragalus, codonopsis, or burdock root in soups.[14]
  4. 4
    Try a holy basil extract to ingest it with any drink. If you'd prefer not to take holy basil as a tea, you can take a concentrated extract with other drinks. Buy a holy basil extract online or from a health food store and add several drops to water or another drink, depending on your preference.[15]
    • You can also rub holy basil extract against the skin to relieve skin irritation or inflammation.
    • Using an extract is an ideal way to take holy basil if you don't want to take a capsule but dislike the herb's distinct taste.

Taking Holy Basil Safely

  1. 1
    Never take more than one dose at a time. If taking holy basil by capsule or extract, avoid ingesting more than the recommended dosage. Although holy basil is safe to ingest, eating too much can strengthen its few side effects.[16]
    • Taking holy basil by tea or soup generally causes the least side effects because it is taken at a lower dose.
  2. 2
    Do not chew holy basil leaves for longer than several minutes. Although holy basil can improve your oral health in small doses, it can eat at your enamel over time. Instead of chewing holy basil, try taking it as a tea or using holy basil toothpaste.[17]
    • In Ayurvedic traditions, chewing holy basil is traditionally a form of desecration.
  3. 3
    Contact a doctor if you experience chronic drowsiness or clotting issues. In some cases, holy basil can cause extreme drowsiness and prevent your blood from clotting after getting injured. Schedule a doctor's appointment before taking holy basil to determine whether the benefits outweigh the potential side effects for you.[18]
    • Do not take holy basil alongside anticonvulsants, sedatives, or blood clot medications, as these can exacerbate holy basil's side effects.
    • High holy basil doses may cause low sperm counts and infertility in men.[19]
  4. 4
    Use holy basil alongside, not instead of, medical treatment. Although holy basil's benefits have been clinically studied, it is not an alternative to prescription medicine. Take holy basil as a supplement to other medications, and consult a doctor or dietitian before adding it to your lifestyle.[20]
    • Do not take concentrated holy basil capsules or extracts while pregnant. Holy basil's side effects in expecting women have not been studied and may cause birth defects.[21]
    • Consult a naturopathic doctor to decide whether holy basil would be the best supplement to your prescription medications.
  5. 5
    Avoid taking holy basil directly before or after surgery. Because holy basil can slow blood clotting, it can increase the risk of bleeding during or after surgery. Stop taking holy basil at least 2 weeks before surgeries to prevent major complications.[22]
