Giloy, known in Ayurveda as Guduchi, is the dried stem of Tinospora cordifolia. Demand rose sharply through the pandemic years and has settled into steady volume across immunity supplements and classical Ayurvedic manufacturing.

Botanical identity and part used

Tinospora cordifolia is a perennial climber of the Menispermaceae family, found throughout tropical India. It has heart-shaped leaves and long aerial roots, and older stems show warty circular lenticels on a light brown surface.

The Ayurvedic Pharmacopoeia of India defines Guduchi as dried, matured pieces of stem. Leaf trades separately and at a lower value, and mixing leaf into a stem lot is a recognised trade shortcut buyers should watch for.

The species identity issue buyers must understand

This is the most important sourcing point on Giloy. Tinospora sinensis and Tinospora crispa are both traded in the Indian subcontinent under the names Guduchi and Giloy, but they are different species.

T. crispa in particular has been associated in published literature with liver injury, and several reported safety cases involving Giloy did not verify which species was actually consumed. Sourcing with confirmed species identity is a genuine due-diligence requirement, not a formality. Ask for it in writing.

Where it grows and when it is harvested

Giloy grows wild across tropical India and is also cultivated on trellises. Rajasthan, Madhya Pradesh, Uttar Pradesh, Maharashtra and Gujarat supply most commercial volume.

The Ayurvedic Pharmacopoeia of India specifies collection during summer, preferably in May. Stems collected then carry better bitter content. The fresh drug is also officially recognised, with a moisture content around 75 per cent.

Processing and grades

Stems arrive in pieces of varying thickness, from about 0.6 to 5 cm diameter. Thickness matters commercially: thicker older stems carry proportionally more starchy pith and less bitter fraction, while younger green stems give higher bitters but lower yield by weight.

Guduchi Sattva, sold in the trade as Giloy Satva, is the water-extracted starch fraction and is an officially recognised Ayurvedic preparation in its own right.

Forms that trade

AV Biotech supplies dried stem pieces, cut and sifted stem, and milled powder at 80 mesh. Extract feedstock is graded on stem diameter and bitter potential. Organic-certified lots are available against advance contract.

Industry applications of Giloy

Giloy sells into a narrower set of categories than most Indian botanicals, with Ayurvedic and immunity-positioned nutraceuticals taking the bulk.

Ayurvedic and pharmaceutical manufacturing

The largest consumer. Guduchi is the base of Amritarishta, Amritottara Kvatha Churna, Guduchyadi Churna, Guduchi Taila and Guduchi Sattva.

These units buy cut stem for decoction preparation and coarse powder for churnas, working to Ayurvedic Pharmacopoeia of India limits. Note that Guduchi's official alcohol-soluble extractive minimum is only 3 per cent, which is low for a stem drug and reflects its high starch content.

Nutraceutical and supplement brands

Supplement manufacturers buy 80 mesh powder and standardised extract for immunity-positioned capsules, tablets, effervescents and daily wellness blends. Extracts are commonly standardised on bitters at 2.5 or 5 per cent, referring principally to clerodane diterpenoid lactones such as columbin and tinosporin.

Herbal beverage and food

Giloy goes into kadha and kwath premixes, herbal teas, juices and immunity shots, usually blended with Tulsi, ginger and black pepper. These formats are the most price-sensitive segment and generally buy general commercial powder.

Extract and phytochemical houses

Extraction units buy cut stem in bulk. They grade on stem diameter, bitters potential and, increasingly, on species verification, since the extract cannot be visually identified once processed.

Cosmetic and personal care

A smaller segment. Extract is used in scalp and skin formulations positioned around purifying and soothing action.

Common product formats

• Amritarishta, Guduchyadi Churna and classical kvatha preparations
• Giloy Satva (Guduchi Sattva) starch preparations and tablets
• Immunity capsules, tablets and effervescent formats
• Kadha and kwath premixes, herbal teas and immunity shots
• Giloy juice and ready-to-drink wellness beverages
• Standardised extracts at 2.5 and 5 per cent bitters
• Multi-herb seasonal wellness and daily tonic blends

Traditional use and current research

The Ayurvedic Pharmacopoeia of India lists Guduchi's actions as Rasayana, Balya, Deepana, Sangrahi, Tridoshashamaka, Raktashodhaka and Jvaraghna. Its traditional applications are recorded as Jvara, Kushtha, Pandu, Prameha, Vatarakta and Kamala.

The Sanskrit synonym Amrita, meaning nectar, reflects the regard the herb has held in Ayurveda. The notes below describe traditional positioning and published research directions, not statements of medical outcome.

Seasonal wellness and immunity positioning

This is Giloy's dominant commercial position. The Ministry of AYUSH has identified Tinospora cordifolia as a botanical of interest for antiviral and antimicrobial research. Brands formulate it into products positioned around seasonal wellness and immune support.

Traditional Jvaraghna use

Jvaraghna is the classical Ayurvedic category relating to fever management, and Guduchi has long been used in this context in kvatha and arishta preparations. This is traditional-use positioning and should be described as such.

Metabolic and general tonic formulations

Classical applications include Prameha, a traditional category relating to urinary and metabolic conditions. Modern products using this angle are generally positioned around general metabolic wellness.

Antioxidant activity

Research has examined the plant's alkaloids, glycosides, lactones and polysaccharide fractions including arabinogalactan. Studies suggest antioxidant and immunomodulatory activity in laboratory and animal models.

Skin and blood-purifier positioning

Raktashodhaka, the traditional blood-purifier category, underpins its use in Ayurvedic skin-wellness formulations.

What buyers should note on claims and safety

Published safety discussion around Giloy is closely tied to species identity, because Tinospora crispa has been linked with liver injury while Tinospora cordifolia is the pharmacopoeial species. Any brand carrying Giloy should hold documented species verification for each lot, and should follow current AYUSH and destination-market guidance on labelling and use.
