Tulsi (Holy Basil) UK Guide: How to Choose

Tulsi, or holy basil (Ocimum sanctum), is one of the most revered plants in India, where it holds a sacred place in daily life and a long history in traditional Ayurveda. This guide covers what to look for when buying tulsi in the UK and how the different forms compare.

What is tulsi?

Tulsi is an aromatic plant in the basil family, distinct from culinary basil. It has been used in Ayurvedic practice for centuries and is traditionally taken as a tea, a tablet, or a fresh leaf. There are several varieties (Rama, Krishna and Vana tulsi), sometimes blended together.

Forms: tablets, capsules and tea

Tulsi is sold as tablets and capsules for a convenient fixed dose, and as loose or bagged tea for the traditional preparation. Tablets suit everyday routine; tea suits those who enjoy the ritual and aroma.

How to choose authentic tulsi

Look for the botanical name (Ocimum sanctum, also written Ocimum tenuiflorum), a named Indian brand, batch lab testing, and a UK seller with fast dispatch. Popular options in our range include Himalaya Tulasi (Holy Basil) Capsules and Baidyanath Tulsi Tablets.

How to take tulsi

Follow the serving stated on your product’s label, or the advice of a practitioner. Tablets and capsules give a fixed daily dose; tulsi tea is brewed in hot water. Tulsi is a food supplement and should not replace a varied, balanced diet.

Tulsi in the classical texts

Tulsi, or holy basil, is Ocimum sanctum (also written Ocimum tenuiflorum), a small aromatic shrub grown in the courtyard of most Hindu homes and worshipped as a living form of the goddess Lakshmi — the “Tulsi Vivah” festival in autumn marks its ritual marriage to Vishnu. The Charaka Samhita names it Surasa; the Bhavaprakasha Nighantu describes tulsi as pungent and bitter in taste (katu, tikta), light and dry in quality, heating in potency (ushna virya) and balancing to kapha and vata. Three varieties are used: Rama tulsi (green leaf, mild), Krishna or Shyama tulsi (purple-tinged leaf, sharper) and Vana tulsi (wild forest basil, Ocimum gratissimum). Many Indian products blend the three.

Traditional dosage forms and how tulsi is taken

The classical forms are fresh leaves chewed in the morning, fresh-leaf juice (swarasa), and a decoction (kwath or kadha) of leaves simmered with ginger and black pepper — the everyday tulsi tea of North India. Dried-leaf powder (churna) is taken with honey or warm water. The Ayurvedic Pharmacopoeia of India lists a traditional daily quantity of 1–3 g of dried leaf powder for adults, or 5–10 ml of fresh juice. Tablets and capsules contain leaf powder or a water extract; tulsi drops are a concentrated liquid extract added to water; tulsi tea bags are simply dried leaf. Follow the directions on the pack you buy.

Comparing the tulsi brands sold in the UK

Organic India built its reputation on tulsi and sells the widest range — certified-organic teas in many blends, 60- and 250-capsule packs; Himalaya’s Tulasi is a standardised extract tablet from the Pure Herbs range; Dabur, Baidyanath and Patanjali sell leaf-powder tablets at the lowest prices; several brands sell tulsi drops (Patanjali’s “Tulsi Panchang” includes all five parts of the plant). The products below are in stock at KantiGlow and shipped from India.

Reading a tulsi label

The label should show Ocimum sanctum or Ocimum tenuiflorum (the same plant) and, ideally, which variety — Rama, Krishna or Vana — or that it is a blend. The part used is the leaf (or “panchang”, all five parts). Extract products should state the extract ratio; teas should state the leaf weight per bag. Certified-organic packs carry the India Organic/NPOP, USDA or EU organic logo. Expect a batch number, expiry date and an MRP in rupees. Tulsi should smell strongly of clove and mint; a faint smell means old leaf.

Fitting tulsi into a daily routine

Ayurveda pays as much attention to when and how a herb is taken as to the herb itself. Tulsi is traditionally taken in the morning, with honey or warm water, or as a tea. Most people find it easiest to attach it to an existing habit — the morning cup of tea, or the evening meal — and to keep to a single product rather than several that overlap. Start with the lowest amount on the pack, stay with it for a few weeks before judging, and keep a note of what you took and when. If you are pregnant, breastfeeding, taking prescribed medicines or under medical supervision, ask a pharmacist or GP before adding any supplement, and stop and seek advice if anything disagrees with you. Tulsi products are food supplements: they are not intended to diagnose, treat, cure or prevent any disease and should not replace a varied, balanced diet.

Storage and shelf life

Dried tulsi leaf loses its clove-like aroma with light and air; keep tea and powder in an opaque, airtight container and use within six months of opening. Powders and dried herbs keep for the period printed on the pack — usually 18 to 36 months — if the pack is resealed and kept cool, dry and out of sunlight; capsules and tablets keep to the printed expiry in their blister or bottle. Damp is the main enemy of Indian powders in a UK kitchen, so keep the churna away from the kettle and the hob. A change of colour or a stale smell means the herb is past its best even if the date says otherwise.
