Amrita: The Classical Name for Giloy — Evidence, Dosage & Safety
TL;DR
Amrita is Tinospora cordifolia: giloy, guduchi. Two human data points pull opposite ways: a small 2005 trial (75 patients) found a stem extract eased allergic rhinitis versus placebo. A 2022 case series linked heavy self-medicated use to 43 acute liver injuries, close to 10% fatal. Large trials are lacking. Respect and a clinician, not a daily DIY decoction.
What it is
Amrita is one of the classical Ayurvedic names for Tinospora cordifolia, a herbaceous vine in the family Menispermaceae native to the tropical Indian subcontinent (medical-college materia medica summary). In Ayurveda the plant goes by many names, including Amrita and Guduchi (Gaduchi). The Ayurvedic Pharmacopoeia of India (Part I, Volume I) is precise: the official drug "guduchi" is the dried mature stem of Tinospora cordifolia. Stem, specifically (Tier 1: API Pt. I Vol. I, Government of India; institutional holding: Wellcome Collection).
This is the same plant as our companion article on giloy. That article covers the modern supplement framing; this page covers the classical "Amrita" framing: the name, the traditional reputation, what the human evidence actually shows. Not duplicated. Read giloy for the contemporary context, this page for the classical entry.
Traditional use
In Ayurvedic literature, Amrita/Guduchi is regarded as the great medicine for jvara (fever). The classical texts give it the epithet of a life-giving (jivanti) drug for chronic and intermittent fevers (same college summary).
The Ministry of Ayush describes Guduchi in Ayurveda as "the best rejuvenating herb" and lists a wide range of traditional applications: antioxidant, anti-hyperglycemic, anti-inflammatory, anti-pyretic, immunomodulatory, and others, characterizing them as well established within the tradition (Ministry of Ayush / PIB, Feb 2022).
These are traditional claims, not clinical proof. I want that sentence underlined. The human trial evidence is next, and it is a separate question.
What modern research says
Allergic rhinitis
The best human trial is a 2005 randomized, double-blind, placebo-controlled trial, and I have to keep saying "best," because it is also nearly the only one. Seventy-five patients with allergic rhinitis received either a Tinospora cordifolia extract or placebo for 8 weeks.
The results: complete relief from sneezing in 83% of patients, from nasal discharge in 69%, from nasal obstruction in 61%, and from nasal pruritus in 71%, versus no relief in roughly 79–88% of placebo patients across the same symptoms. Eosinophil and neutrophil counts fell; goblet cells disappeared from nasal smears in the TC group. The authors reported the extract was well tolerated (Badar et al., Journal of Ethnopharmacology 2005).
Strong numbers. One small trial from one center, testing one specific extract, never replicated at scale. I would not generalize this to every giloy product on a shelf, and neither should you.
What the evidence does not support (yet)
A 2024 comprehensive review catalogues promising in vitro and animal data: antioxidant, anti-inflammatory, immunomodulatory, antimicrobial. But it notes that large-scale clinical trials are lacking and most human studies are small, open-label, or observational. Its explicit call: large randomized trials to confirm efficacy (Sharma et al. 2024 review).
And then there is the sentence I make everyone read twice. The authors of the largest published liver-injury case series put it bluntly: "Studies on Giloy are mostly preclinical with no strong evidence for use in humans to prevent or treat any disease" (Kulkarni et al., multicenter study). Claims about immunity-boosting, diabetes, or cancer treatment are ahead of the data. Well ahead.
Dosage
There is no established dose. The Badar 2005 trial used a T. cordifolia stem extract for 8 weeks, and the published abstract does not state the extract dose (PubMed abstract). The Pharmacopoeia defines the drug's identity (dried mature stem), not a consumer dose. Do not treat the trial regimen as a personal recommendation. There is nothing here to self-dose from.
Safety & contraindications
This is the section that decides whether you should touch this plant at all. Read it fully.
In the 8-week allergic-rhinitis RCT, the extract was reported as well tolerated (Badar et al.). That is the reassuring data point, and it covers 8 weeks in a supervised trial. Nothing more.
The serious safety signal comes from a different context: a 2022 multicenter Indian study pooled 43 patients with acute liver injury temporally associated with giloy use. Most had self-medicated with pure giloy decoctions bought locally: mean intake around 40.8 mL/day, median 46 days to symptom onset. The injury showed autoimmune features. Close to 10% of patients died within 2 months; nearly 5% required liver transplantation. Causality assessment rated probable liver injury in 67.4% (Kulkarni et al.).
The Ministry of Ayush disputes a causal link. It calls media reports misleading, states that available data show Guduchi does not produce toxic effects at appropriate doses, and emphasizes the herb must be used in an appropriate dose as prescribed by a qualified physician (PIB, Feb 2022).
My honest reading: short-term use was uneventful in one small trial, but unsupervised heavy use has been temporally linked to severe liver injury. Hold both. People with liver disease or abnormal liver tests should avoid it. Anyone considering it should talk to a qualified clinician first, not self-prescribe decoctions.
FAQs
Is amrita the same as giloy?
Yes. Amrita is the classical Sanskrit name; giloy (guduchi) is the common name for the same plant, Tinospora cordifolia. Our giloy article covers the modern supplement framing; this page covers the classical entry.
Does amrita help with allergies?
One small 2005 randomized trial (75 patients, 8 weeks) found a Tinospora cordifolia extract significantly reduced allergic rhinitis symptoms versus placebo (Badar et al.). A single small trial: promising, not proven. I would not buy allergy relief on this evidence yet.
Is giloy bad for the liver?
A 2022 multicenter Indian study reported 43 cases of acute liver injury with autoimmune features temporally linked to giloy, mostly from self-medicated decoctions, and about 10% of those patients died (Kulkarni et al.). The Ministry of Ayush disputes causality and stresses proper dosing under qualified guidance (PIB). Caution is warranted, especially with any liver condition. This is the sharpest safety signal on this page.
What dose was used in the allergy trial?
The trial used a T. cordifolia stem extract for 8 weeks, and the published abstract does not state the dose. There is no established dose. Do not self-dose from this article. There is no number to self-dose from.
Can I take giloy daily as an immunity booster?
No large trial establishes that daily giloy prevents illness or is safe long-term, and most liver-injury cases involved self-medicated daily decoctions (Kulkarni et al.). Talk to a qualified practitioner instead of self-prescribing. Daily DIY decoctions are exactly the pattern in the injury reports.
Sources
The allergy trial is Badar VA et al., "Efficacy of Tinospora cordifolia in allergic rhinitis," Journal of Ethnopharmacology 2005;96(3):445–449, PMID: 15619563 (PubMed), the one human RCT this plant has, and I cite its limits as carefully as its results. The liver-injury data are from Kulkarni AV et al.'s multicenter nationwide study, "Tinospora Cordifolia (Giloy)–Induced Liver Injury During the COVID-19 Pandemic" (2022) (PMC9134809), including the authors' own blunt verdict on the state of giloy evidence. The Ministry of Ayush response, "It is misleading to relate Guduchi to liver damage" (16 Feb 2022), is via PIB (release). The preclinical-but-no-large-trials picture comes from Sharma et al.'s 2024 comprehensive review of phytochemistry and pharmacological activities (IJPS). The pharmacopoeial identity of the drug is via the Wellcome Collection's holding of the Ayurvedic Pharmacopoeia of India, Part I, Volume I (Wellcome), and the traditional-use background draws on the medical-college materia medica summary (PDF).
