November 15, 2021by Anzen_Exports0

Native to Southeast Asia and the Indian subcontinent, Ocimum tenuiflorumor, commonly known as the Holy Basil or Tulsi, is renowned for its various therapeutic properties. It is rich in antimicrobial, antidiabetic, adaptogenic, hepatoprotective, anti-inflammatory, radioprotective, anticarcinogenic, neuroprotective, immunomodulatory and cardioprotective properties. Also referred to as ‘Hot Basil’ owing to its peppery taste, Holy Basil is known to decrease inflammation, lower blood sugar levels and even act as an antioxidant.

Being host to a plethora of beneficial constituents viz. eugenol, ursolic acid, rosemarinic acid, carotenoids, caryophyllene, oleanolic acid, vitamin C, iron, calcium, zinc, and chlorophyll – the uses of holy basil are myriad. Commonly prescribed for coughs and colds, asthma and bronchitis, this herb also promotes circulation, normalizes blood pressure and is often combined with other herbs to address heart issues. [1, 2]

Holy Basil: A herb for all reasons

Mechanism of action [3]

The presence of a complex pool of phytochemicals is responsible for the rich medicinal properties attributed to Holy Basil:

  • Eugenol: Lowers blood glucose levels, treats digestive and respiratory problems
  • Ursolic acid: Has antioxidant, anti-inflammatory, antibacterial, anticancer, antifungal properties
  • ß-caryophyllene: Possesses anti-inflammatory, analgesic and antipyretic effects
  • 1,8-Cineole: This is beneficial in cough, allergies, asthma relief and immune support

Side effects

It is safe when it entails short-term usage: 500 mg daily for 60-90 days. It might cause nausea or diarrhoea. There isn’t enough reliable information available to know if it is safe to use long-term. [4]

Precautions [4]

  • Pregnancy: Consumption of Holy Basil is probably unsafe during pregnancy or when trying to conceive. In animal testing, large doses of the herb have reduced the chances of getting pregnant or have caused abortion. The data is, however, still unconfirmed in humans.
  • Breastfeeding: Enough reliable information about the safety while breastfeeding isn’t available. So it is best to consult the family physician before consumption.
  • Hypothyroidism: Holy Basil lowers thyroxine levels and could worsen hypothyroidism.
  • Surgery: The herb may slow blood clotting – it is advised to prevent usage at least two weeks before a scheduled surgery.

Interactions [4]

  • Anticoagulant / Antiplatelet drugs interact with Holy Basil.
  • Since this herb may slow blood clotting, interaction with blood clotting medicines is possible. Slow clotting might increase the chances of bruising and bleeding.
  • The sedative Pentobarbital interacts with Holy Basil. Since Pentobarbital causes drowsiness, combining it with Holy Basil seed oil might cause excessive drowsiness.
