Ayurvedic Benefits and Uses of Tulsi (Holy Basil)

Ayurvedic Benefits and Uses of Tulsi (Holy Basil)

The Ayurveda Experience June 17, 2017

Ayurveda refers to tulsi or Holy Basil as “the incomparable one,” “mother medicine of nature” and “the queen of herbs”. Let’s take a look at benefits, uses, research, and contraindications of tulsi.

It is revered as an elixir of life for both its medicinal and spiritual properties. It belongs to the mint family and has two main varieties.

The greener variety is called rama tulsi and the greenish-black variety is called krishna tulsi.

Holy Basil, Ocimum sanctum, should not be confused with Sweet Basil, Ocimum basilicum, which is commonly used for culinary purposes.

In Hinduism, tulsi is worshipped as a goddess and every part of the tulsi plant is revered and considered sacred, including the leaves, stem, flower, root, seeds, and oil.

Every Hindu household has a tulsi plant which is used as raw leaves or as a leaf tea for spiritual and religious practices. Its strong eugenol laden smell is believed to repel mosquitoes, flies, and insects.

Tulsi leaves are believed to help lower materialistic desires and lust. It was taken daily by students in ancient Indian boarding schools known as ‘Gurukulas’ and also by followers of the spiritual path.

Hundreds of thousands of tulsi plants have been planted around the Taj Mahal in Agra, India to help protect the iconic marble building from environmental pollution and damage.

An easy way to use tulsi daily is as follows. Take 10-12 tulsi leaves, wash them and shred them.

If fresh leaves are not available, take ½ tsp of dry tulsi leaves. Boil them in about 1 cup of water on a medium flame and reduce to half. Strain and enjoy.

You may add a little ginger and clove while making this tea for extra benefit. Avoid adding milk as milk is incompatible with tulsi according to the Ayurvedic texts. Read on for tulsi’s proven benefits as seen in research studies.

Modern Research On Tulsi Benefits

Tulsi (Holy Basil): Tulsi Benefits, Uses, Research

Holy Basil's beneficial effects are found across quite a few categories of medicinal activities, including anti-bacterial, anti-acne, anti-stress, antilipidemic, antidiabetic, and blood glucose-lowering properties.

1. Anti Bacterial Activity

Research has shown strong antibacterial activity of the extract of Holy Basil.

In the study, leaf extracts of holy basil and other plants inhibited the growth of the test organisms and exhibited antibacterial activity.

However, the majority of the bacterial species were susceptible to all the extracts of O. sanctum, when compared to A. vera and S. grandiflora.

This work supports the traditional use of these plants and the therapeutic value against bacterial pathogens so that they can be alternate antibacterial agents in the future.

2. Anti Acne Effect

In another study Holy basil oil was tested in trials as an antibacterial treatment for acne.

It produced good results. An excellent study of oils from four types of Ocimum species found that although there was variation in contents all oils were found to have antimicrobial activity at fairly low dilutions.2

In another study it was shown that the linolenic acid present in basil is responsible for its anti-inflammatory effect in acne.

This also has been observed when 2% Ocimum oil is used with Aloe vera gel. The anti-acne activity increases due to the synergistic effect of these agents.3

3. Anti Stress Properties

Male mice were used as the subjects of a study demonstrating the lowering of serum concentrations of cortisol and glucose through the use of plant extracts of Ocimum sanctum.

Lipid peroxidation was not enhanced which is good for the health of the arteries.

The study also showed an anti-peroxidative effect from the extract, suggesting a potential regulation of corticosteroid-induced diabetes.4

Other studies examined the use of Ocimum sanctum to help the subjects better withstand the stress of chronic exposure to noise.

The study used albino rats. The administration of the extract of Holy Basil prevented noise-induced increases in the levels of the neurotransmitters dopamine and serotonin turnover in specific brain regions.

The noise-induced increases were prevented and normal levels of the neurotransmitters were not affected.5, 6

In still another study using animal models treatment with Ocimum sanctum was shown to be effective in treating noise-induced stress changes, including changes in cortisol levels.7

4. Anti Lipidemic Properties

Ocimum sanctum and eugenol lowered restraint stress-induced cholesterol levels. They also effectively lowered the restraint stress-induced elevations in liver enzymes namely lactate dehydrogenase (LDH) and alkaline phosphatase.8

In another study, a reduction in total cholesterol, triglyceride, phospholipids and total lipids in the liver, kidney, or heart was demonstrated by the addition of Ocimum sanctum leaf powder to the diet of diabetic and non-diabetic rats.9

5. Glucose Lowering Effect

Reduction of fasting blood sugar was observed with the addition of Ocimum sanctum leaf powder to the diet of diabetic rats; uronic acid and total amino acids were also reduced.9

6. Hepatoprotective Properties

A study showed significant hepatoprotection from the use of a Holy Basil alcoholic leaf extract when used alone, and synergistic hepatoprotection in conjunction with silymarin.10

7. Anti Viral Activity

A study by the defense research institute, Gwalior, India, showed a significant effect on the swine flu virus.11
