Vatagajankush Rasa: Benefits, Evidence & Safety

TL;DR

Vatagajankush Rasa is a classical herbo-mineral Ayurvedic formula for Vata disorders such as sciatica and paralysis, containing mercury, arsenic and aconite-derived ingredients. A 2019 open-label study of 30 stroke patients reported improvement after 7 days, but it had no control group. Given the toxic ingredients, use only under qualified supervision.

Heavy-metal and toxicity warning: Vatagajankush Rasa deliberately contains mercury (as Rasasindhura), arsenic (as Hartala) and Vatsanabha (Aconitum ferox, a plant whose alkaloids are documented cardiotoxins and neurotoxins). This is one of the highest-risk classical formulations. It must only be used under the supervision of a qualified practitioner, from a tested, reputable source: never self-prescribed.

What it is

Vatagajankush Rasa (also rendered Vat Gajankush Ras / Vatagajankusha Rasa) is a classical rasa, a herbo-mineral formulation of the Rasa Shastra tradition, referenced in the Bhaishajya Ratnavali, Vatavyadhi Adhikara (verses 116–120) (Yadu Gopan et al., J Ayurveda Integr Med Sci 2019; Shete, JAIMS 2025 literature review).

Its ingredients, as given by classical reference sources, are: Rasasindhura (red sulphide of mercury), Lauha Bhasma (calcined iron), Swarnamakshika Bhasma (calcined copper–iron pyrite), Shuddha Gandhaka (purified sulphur), Shuddha Hartala (purified orpiment: arsenic trisulphide), Haritaki (Terminalia chebula), Karkatashringi (Pistacia integerrima), Shuddha Vatsanabha (Aconitum ferox), Trikatu (dry ginger, black pepper, long pepper), Agnimantha (Premna spp.), and Shuddha Tankana (borax), triturated with the juices of Mundi (Sphaeranthus indicus) and Nirgundi (Vitex negundo) (classical Ayurvedic reference aggregator, Tier 3). The 2019 clinical study describes it concordantly as "a combination of vyosha, bhasmas, vatsanabha, karkatasringi, haritaki etc." (JAIMS 2019). Composition varies by manufacturer, so label ingredients should always be checked.

Traditional use

Classical sources indicate Vatagajankush Rasa for vata vyadhi, disorders of aggravated Vata, including pakshaghata (paralysis/hemiplegia), gridhrasi (sciatica), joint and muscular pains, arthritis, avabahuka (shoulder/arm pain), manya stambha (neck rigidity) and urustambha (thigh stiffness), framed as pacifying Vata and Kapha (classical Ayurvedic reference aggregator, Tier 3; JAIMS 2025 review). These are traditional indications, not evidence of efficacy.

What modern research says

Open-label study in Pakshaghata (stroke), 2019

The most directly relevant study is an open-label, single-arm prospective clinical study: of 32 registered patients with Pakshaghata (cerebrovascular accident due to infarct), 30 completed treatment with Vatagajankusha Rasa 125 mg twice daily after food, plus 3 g Pippali churna and 15 ml Manjishta kwatha twice daily as carriers, for 7 days. The authors reported statistically significant improvement in primary and secondary outcome measures (p < 0.05) (Yadu Gopan et al., JAIMS 2019) (open-label clinical study).

Important limitations: there was no control or placebo group, only 30 patients finished, treatment lasted just 7 days, and the rasa was given together with two other preparations: so the improvement cannot be attributed to Vatagajankush Rasa alone, nor distinguished from natural recovery or placebo effects.

Small study in Gridhrasi (sciatica)

A small clinical study published in the International Journal of Advanced Research (2019) tested Vatagajankusha Rasa in Gridhrasi (sciatica) and reported symptomatic improvement (IJAR 2019) (small clinical study). A 2025 JAIMS literature review on Vatgajankush Vati in sciatica summarizes the classical rationale and contemporary reports but adds no new trial data (Shete, JAIMS 2025) (literature review).

Bottom line: the evidence consists of small, short, uncontrolled studies: often testing the formulation as part of a combination. There are no large randomized controlled trials of Vatagajankush Rasa, and its efficacy remains unproven.

Dosage

In the 2019 open-label study, patients received 1 tablet (125 mg) twice daily after food for 7 days, with 3 g Pippali churna and 15 ml Manjishta kwatha twice daily as carriers (JAIMS 2019). This is the dose used in that small study: not a general recommendation. Given the mercury, arsenic and aconite content, dosing must come only from a qualified practitioner experienced in rasa medicines.

Safety & contraindications

This formulation contains mercury, arsenic AND aconite: the strongest cautions apply:

• Mercury: it contains Rasasindhura (mercury–sulphur compound). NCCIH warns that "some Ayurvedic preparations may contain lead, mercury, or arsenic in amounts that can be toxic" (NCCIH: Ayurvedic Medicine In Depth). A JAMA-published survey found about one in five Ayurvedic products bought online contained lead, mercury or arsenic, with metal-containing rasa shastra medicines showing higher metal prevalence (40.6%) and higher median mercury concentrations than herbal products (Saper et al., JAMA 2008).
• Arsenic: it contains Hartala (arsenic trisulphide). NCCIH notes that "although rare, Ayurvedic products may cause arsenic poisoning" (NCCIH).
• Aconite: Vatsanabha is Aconitum ferox. Aconitine and related Aconitum alkaloids "are highly toxic cardiotoxins and neurotoxins," and "the use of a larger than recommended dose and inadequate processing increases the risk of poisoning" (Chan, Clin Toxicol 2009). Severe poisoning can cause dangerous heart-rhythm disturbances.
• Purification claims are unproven. Tradition holds that shodhana renders these ingredients safe; this has not been established by controlled human safety trials.
• Pregnancy, breastfeeding, children: avoid absolutely. No safety data exist, and mercury, arsenic and aconite each carry severe risk in these groups. NCCIH advises pregnant or nursing users to consult their healthcare provider, as some Ayurvedic products "could be harmful" (NCCIH).
• Heart, liver and kidney conditions: consult a physician first: never use without medical oversight.
• Product variability and duration: metal and alkaloid content varies between manufacturers and batches; use only tested products, at the prescribed dose and duration, never alongside other metal-containing medicines, and never exceed the prescribed dose.
• Self-medication may be life-threatening. Keep out of reach of children. If unusual symptoms occur, especially numbness, palpitations, nausea or weakness, stop use and seek emergency medical advice.

FAQs

What is Vatagajankush Rasa made of?

It is a herbo-mineral tablet containing Rasasindhura (mercury–sulphur), calcined iron and copper–iron pyrite, sulphur, Hartala (arsenic trisulphide), Vatsanabha (Aconitum ferox), Haritaki, Karkatashringi, Trikatu, Agnimantha and borax, processed with Mundi and Nirgundi juices. Composition varies by manufacturer (classical aggregator, Tier 3).

What is it traditionally used for?

Classical texts indicate it for Vata disorders: paralysis/hemiplegia (pakshaghata), sciatica (gridhrasi), joint and muscular pains, arthritis, neck rigidity and thigh stiffness. These are traditional indications, not proven effects (JAIMS 2025 review).

Does research show it works for paralysis or sciatica?

Only weakly. A 2019 open-label study of 30 stroke patients reported improvement after 7 days of the formulation plus two companion medicines, and a small 2019 study reported benefit in sciatica: but neither had a control group. No large randomized trials exist, so efficacy is unproven (JAIMS 2019).

What dose was used in the study?

The 2019 study used 1 tablet (125 mg) twice daily after food for 7 days, with Pippali churna and Manjishta kwatha as carriers. That is a study protocol, not a recommendation: dosing must come only from a qualified practitioner (JAIMS 2019).

Why is it considered high-risk?

It deliberately combines three toxic ingredients: mercury, arsenic and aconite alkaloids (documented cardiotoxins and neurotoxins). Independent testing has repeatedly found heavy metals above safe limits in Ayurvedic metal-containing products (NCCIH; Chan 2009).

Can it be used in pregnancy or given to children?

No: absolutely avoid. There are no safety data, and mercury, arsenic and aconite each pose severe risks in pregnancy, breastfeeding and childhood. Use only under strict supervision of a qualified practitioner, if at all (NCCIH).
