Holy basil is an important medicinal plant considered sacred by the Hindus in the subcontinent of India. It is mentioned in the Indian collection of Vedic Sanskrit hymns called the Rig Veda around 1500 BC, while holy basil is also mentioned in the ancient Hindu religious texts parts of the Vedas called the Purana.

Holy basil is a perennial aromatic shrub that belongs to the Lamiaceae family. The holy basil plant is thought to be native to tropical Asia and north central India; however, it now grows throughout various tropical climates around the globe, and is respected for its many health benefits.

In the various traditional Southeast Asian systems of medicine, the different parts of tulsi have been used for medicine, including the flowers, stem, leaves, seeds, root, and even the whole plant. It has a characteristic peppery, light lemon scent, along with purple-pink flowers and oval-shaped leaves with a slightly sharp tip, and somewhat toothed edges.

There are two main types of tulsi—the Shyam tulsi with dark pinkish-purple stem and leaves and Rama tulsi with a white stem and green leaves. Both holy basil types smell similar, and possess the same benefits. A quarter cup of fresh tulsi leaves contains 31% of your recommended daily vitamin K, as well as some chlorophyll, zinc, iron, vitamin A, vitamin C, manganese, folate, potassium, magnesium, and calcium.

5 Health Benefits of Holy Basil

Tulsi is naturally designed to help protect tissues and organs against physical stress from prolonged physical exertion, and also chemical stress from heavy metals and industrial pollutants.

Holy basil is loaded with the fat-soluble vitamin K, which is crucial for heart health and bone health. Vitamin K benefits blood clotting, bone mineralization and bone density, brain function, and health metabolism and cellular health. Holy basil could also fight bacteria in the mouth, which can lead to bad breath, tartar, plaque, and cavities.

Its infection-fighting properties could possibly protect against viruses and bacteria, which also make holy basil great for fevers.

The following is further detail on some of the key health benefits of holy basil.

1. Fights and Prevents Cancer

Research shows that holy basil could not only fight cancer, but it could also help prevent it. Research published in the journal Nutrition and Cancer in 2013 suggests that phytochemicals in holy basil prevent chemical-induced lung, oral, liver, and skin cancers due to increased antioxidant activity, inducing cancer cell death, altering healthy gene expressions, and preventing blood vessel growth that contributes to cell growth and stopping the spread of cancer from one organ to another.

Holy basil may also protect the body from radiation poisoning, while healing damage from radiation cancer treatment. Studies published in the Alternative Medicine Review in 2009 indicate that holy basil protects against toxic chemical-induced injury from increasing the body’s antioxidant levels, including glutathione that helps fight free radical damage due to toxic agents and a lack of oxygen.

2. Protects Against Diabetes

Holy basil may also have the ability to regulate blood sugar levels and prevent diabetes symptoms, such as excess insulin in the blood, insulin resistance, high cholesterol, weight gain, and hypertension. A study published in the International Journal of Clinical Pharmacology Therapy showed that holy basil could decrease blood glucose, regulate abnormal lipid profiles, and protect the kidneys and liver from metabolic damage due to high glucose levels.

3. Lowers Cholesterol

A study published in the journal Life Sciences in 2006 found that rabbits had significant changes in fat molecules when they consumed fresh holy basil leaves. As a result, they had higher high-density lipoprotein (HDL) or good cholesterol and reduced low-density lipoprotein (LDL) or bad cholesterol. Other studies found that the eugenol in holy basil could reduce stress-induced cholesterol levels, while reducing total cholesterol in the liver, kidney, or heart after consumption of holy basil leaf powder.

4. Balances Hormones/Reduces Stress and Anxiety

High cortisol is a common problem. Cortisol is a stress hormone that has a big impact on memory, learning, bone density, immune function, heart disease, weight gain, sexual health, and sleep. Holy basil, however, is able to regulate cortisol levels and naturally balance hormone levels. A study published in the Nepal Medical College Journal in 2008 found that people that took 500mg of holy basil extract daily felt less stress, anxious, and depressed, while also being more social than before. The researchers concluded that holy basil may be a useful treatment for generalized anxiety disorder.

5. Fights Acne and Skin Problems

Holy basil kills infections and bacteria, so it might be ideal for acne and other skin problems such as raised scars, keloids, and mouth ulcers. Holy basil is generally safe for the skin, and it heals skin infections both externally and internally. Research shows that it could naturally treat acne when combined with coconut oil as a carrier, which effectively helps the herb absorb into the skin.
