Holy basil, which is known for its healing properties, has a vibrant history that dates back to 3000 years in India. For millennia, holy basil plant has adorned temples and houses throughout the country and has been revered as ‘Mother Medicine of Nature’ and the ‘Elixir of Life.’ Used in ancient Ayurvedic medicine, the leaves are regarded as anti-stress agents (adaptogens) and have been widely used to promote health throughout the body.

Aside from being found in India and cultivated across Southeast Asia, holy basil is also grown throughout Africa and Madagascar. However, it is considered an invasive weed in the Pacific Islands.

Generally, the leaf is the part used in a medicinal capacity. The herb is taken traditionally as a tea made from the leaves, fresh leaf, dried extract powder, or mixed with ghee.

Health Benefits of Holy Basil (Tulsi)

In the past few decades, several Indian researchers and scientists have studied the medicinal properties and pharmacological effects of tulsi on the reproductive system, immune system, cardiovascular system, central nervous system, urinary system, gastric system, and blood biochemistry.


No wonder scientists have described Holy Basil as “an herb for all seasons.”

Due to results of their research, the plant is found to have several benefits, including:

  1. Relieves headaches
  2. Fights acne
  3. Protects against diabetes
  4. Fights convulsive activity in epilepsy
  5. Fights cancer
  6. Aids in cases of mercury poisoning
  7. Balances hormones
  8. Fever Remedy
  9. Cures respiratory disorders
  10. Supports eye health

Protects against diabetes

Several human clinical trials and animal test tube experiments indicate that holy basil has anti-diabetic activity. Studies indicate that holy basil can correct abnormal lipid profiles, reduce blood glucose, and protect the kidneys and liver from metabolic damage due to elevated glucose levels.

Fights cancer

Holy basil prevents and treats cancer. In research, people who consume holy basil regularly are less likely to develop cancer cells and are less likely to have their immunity compromised. The herb’s phytochemicals prevent chemically induced oral, liver, skin, and lung cancers because they alter healthy gene expressions, increase antioxidant activity, prevent blood vessel growth that leads to cancer cell growth, induce cancer cell death, and stop metastasis (the spread of cancer from organ to organ).

Holy basil also heals radiation treatment damage and protects the body from radiation poisoning. The herb raises the body’s levels of antioxidant molecules (including glutathione) and enhances antioxidant enzyme activity.

Cures respiratory disorders

Holy basil can cure various respiratory disorders including acting as a natural remedy for bronchitis, which is a deep cough that normally occurs with another upper respiratory infection type, such as flu or the cold. The leaves’ components (cineole, eugenol, and camphene) provide relief from congestion and other respiratory disorder symptoms. Holy basil is also a natural asthma remedy as it allows for easier breathing and relieves congestion.

Supports eye health

The eyes are prone to fungal, bacterial, and viral infections that may be dangerous. Tulsi can fight against boils and pink eye (conjunctivitis). The herb also has soothing and anti-inflammatory properties that protect the eyes from free radicals and environmental damage. The leaves also prevent several eye issues including ophthalmia, vision defects, and cataracts. The herb also naturally treats macular degeneration and glaucoma.

Good vitamin K source

The fat-soluble vitamin K is vital for heart health and bone health. Vitamin K is involved in blood clotting and bone mineralization; it also helps keep a healthy metabolism, maintains cognitive function, and protects against cancer. A cup of holy basil leaves has more than the required daily vitamin K amount, making the herb the best source for vitamin K deficiency prevention. The herb is also beneficial for digestive health and bone density.

Balances hormones

Also known as the stress hormone, cortisol can impact memory, learning, bone density, immune function, heart disease, and weight. Thus, elevated cortisol levels may be harmful. Holy basil can naturally balance hormone and cortisol levels. By adding the herb to your foods, you get your body to run smoothly. Tulsi will additionally help to beneficially regulate neurotransmitters in the brain, such as dopamine and serotonin.

Many in vitro, animal and human studies attest to tulsi having multiple therapeutic actions including adaptogenic, antimicrobial, anti-inflammatory, cardioprotective, and immunomodulatory effects – National Institute of Health

Ayurvedic Energetics

In Ayurveda, holy basil’s taste is bitter and pungent. Its post-digestive effect is pungent. With its heating energy, the herb has dry and light qualities. It balances the Ayurvedic doshas of vata and kapha, and it increases pitta.

For thousands of years, tulsi has been used around the world by many cultures. In the Vedas, it is described as India’s most sacred plant and was used traditionally in Ayurveda medicinal formulas and religious ceremonies.
