Heavy Metals in Ayurvedic Medicines: Kamini Lead Poisoning Case

From Rasa Shastra to Grocery Counter: What Ayurveda Lost in the Age of Commercialisation

He came to the hospital with stomach pain, weakness, and severe anaemia. Nothing initially suggested poisoning or addiction. But after repeated questioning, a detail emerged. For months, he had been self-medicating with an over-the-counter Ayurvedic product called Kamini, bought from a local grocery store.

This is not an isolated case. It is now a documented pattern, appearing in addiction clinics across India, Australia, and the UK. And it begins at a grocery store shelf.

What Is Kamini?

Kamini Vidrawan Ras is an Ayurvedic formulation sold in small pellet or tablet form, typically marketed for male sexual health. It is widely available over the counter at Ayurvedic and grocery stores across India, and has been illegally imported into countries including Australia, New Zealand, and the United Kingdom.

What many buyers do not know is that Kamini contains Papaver somniferum, the opium poppy. Reported opium content ranges from approximately 2–20 mg per tablet. In most countries, substances derived from the opium poppy are available only by prescription.

This does not mean all Ayurvedic medicines are unsafe. Many are purely herbal and widely used without serious harm. The concern is about certain commercially sold products that contain opioids, heavy metals, or poor manufacturing oversight.

The Evidence: What Published Research Says

Opioid Dependence

Reports from India and Australia are now describing a similar pattern repeatedly: men developing opioid dependence, anaemia, abdominal pain, and elevated blood lead levels after prolonged Kamini use. Some required chelation therapy for lead toxicity, while others needed long-term opioid substitution treatment.

A 2024 case series from the Department of Psychiatry and Haematology at Christian Medical College, Ludhiana, described three male patients who presented with abdominal pain, generalised weakness, and anaemia. All were found to be opioid-dependent due to Kamini use, with significantly elevated blood lead levels. All three responded to chelation therapy.

A 2022 case series from an addiction medicine clinic in Australia described 12 patients who developed opioid use disorder after using Kamini, with durations of use ranging from 6 months to 8 years. Eleven of the twelve were born in India. Nine required buprenorphine maintenance treatment.

Similarly, another Australian case series reported another cohort of 12 male patients, aged 27–41, predominantly of north Indian origin, all treated with opioid substitution therapy for Kamini dependence.

A 2025 Indian case series documented five males with confirmed opioid dependence who had transitioned from natural opium (afeem/doda) to products like Kamini and Barshasha, believing them to be safer and non-addictive.

Heavy Metals Contamination in Ayurvedic Medicines

Another harm is heavy metal contamination. Heavy metal exposure associated with Ayurvedic medicines may arise through multiple pathways, including intentional addition of metallic preparations in Rasa Shastra formulations, contamination of raw materials, inadequate purification (Shodhana), poor manufacturing practices, or deliberate adulteration outside classical methods.

A systematic review of heavy metal toxicity from Indian traditional medicine systems identified 220 documented cases from 51 case reports and 14 case series. Lead was the most common culprit (n=156), followed by mercury (n=47) and arsenic (n=11). Among the analysed drug samples, 83.7% contained concentrations of heavy metals above permissible levels.

A 2022 study from PGIMER Chandigarh tested common over-the-counter Ayurvedic preparations from local markets using inductively coupled plasma mass spectrometry (ICP-MS), finding toxic concentrations of lead, mercury, arsenic, and cadmium in a significant proportion of samples.

A retrospective study of 386 CAM products from 91 patients presenting with adverse events at a South Indian tertiary centre (2021–2023) found mercury exceeding WHO limits in 34% of products, cadmium in 25%, arsenic in 21%, and lead in 14%.

The clinical picture of lead toxicity from Kamini is often non-specific, including abdominal pain, weakness, anaemia, basophilic stippling on peripheral blood smear, and elevated blood lead levels. These symptoms can mimic many common gastrointestinal or haematological conditions.

Why cases are frequently missed:

• patients often do not disclose Ayurvedic or OTC product use unless specifically asked
• clinicians may not suspect heavy metal toxicity in younger patients
• symptoms are non-specific and mimic common gastrointestinal or haematological disorders
• toxicology testing is not routinely performed in many settings

Beyond addiction medicine and haematology, some gastroenterologists in north India describe encountering severe chronic gastrointestinal complications in long-term Kamini users, including profound opioid-related gut dysmotility and suspected stricture disease. Although systematic published data remain limited, clinicians describe severe long-term gastrointestinal and dependency-related complications among chronic users of opioid-containing OTC preparations, suggesting that the burden of morbidity may be substantially under-recognised.

What Classical Ayurveda Actually Says About Metals

The use of metals in Ayurvedic medicine is not adulteration. It is called Rasa Shastra, the branch of Ayurveda focused on the therapeutic use of metals, minerals, and mercury. Rasa Shastra texts, developed primarily from the 8th century onwards, describe elaborate procedures for purifying toxic substances before therapeutic use.

The main process is Shodhana (purification). The Charaka Samhita acknowledges the existence of sthavara visha (poisons of mineral and plant origin) and describes the conditions under which toxic substances can be rendered medicinal.

Proponents of Rasa Shastra argue that properly prepared bhasmas undergo physicochemical transformation during purification and incineration processes, potentially altering toxicity profiles. However, modern evidence regarding long-term safety, standardisation, and reproducibility remains limited and controversial.

A foundational principle from the Charaka Samhita says:

नास्त्यभोज्यं नास्त्यभेष्यं नास्त्यव्याधिकरं जगत्। योगस्तु विद्यते सर्वं नैव यन्न भिषग्विदुः॥

Nāstyabhojyaṃ nāstyabheṣyaṃ nāstyavyādhikaraṃ jagat | Yogastu vidyate sarvaṃ naiva yanna bhiṣagviduḥ ||

There is nothing in the world that is not food, not medicine, not capable of causing disease. What matters is the knowledge of how to use it rightly, and that is the domain of the physician

— Charaka Samhita, Sutrasthana

Charaka did not say metals are harmless. He said that everything, including what is toxic, can be medicinal when used correctly, by someone who knows. The trained Vaidya, the precise method, the proper Shodhana, the correct dose are essentially required.

The ancient scholars, Acharya Charaka, Sushruta, and Vagbhata, were aware of the therapeutic value of metallic and mineral-origin substances, but restricted their use carefully. Rasashastra, formalised as a discipline after the 8th century, encoded them into elaborate purification protocols.

The classical system was never intended for metal-containing preparations to be sold over the counter, self-prescribed, and consumed without physician guidance.

The required essentials built into Rasa Shastra, including Shodhana, dosage control, and physician supervision, are what the OTC market bypasses entirely. Many qualified Ayurvedic practitioners do not endorse the unsupervised OTC use of formulations such as Kamini, particularly outside of physician supervision and classical therapeutic indications

The Line Between Classical Practice and the Commercial Market

Metals (bhasmas) are considered therapeutically essential in Rasa Shastra. They are added after Shodhana in classical formulations. However, many recent reports demonstrate that herbal medicines are being adulterated with toxic quantities of heavy metals far beyond any therapeutic intent.

The Government of India has mandated that Ayurvedic products specify their metallic content on labels. However, prominent Ayurvedic scholar M.S. Valiathan has pointed out that without robust post-market surveillance and adequate laboratory infrastructure, meaningful quality control of Ayurvedic medicines remains extremely difficult to enforce in practice.

India currently lacks a clearly visible and consistently enforced surveillance framework specifically targeting opioid-containing Ayurvedic OTC products. Meanwhile, the patient trusts the label.

The Global Scenario

What makes this issue more concerning is that it is no longer limited to local markets in India.

New Zealand’s National Public Health Service reported 22 cases of elevated blood lead levels linked to Ayurvedic medicines since October 2023, with implicated products sourced both internationally and locally.

In Australia, the Therapeutic Goods Administration (TGA) has issued formal warnings about Kamini tablets, confirming they contain scheduled substances available only by prescription. Despite this, supply through Indian grocery stores persists.

The global reach of this problem shows two sides. One, the deep trust Indian communities place in traditional medicine, wherever they are, and second, the complete absence of international harmonisation in regulating herbal products that cross borders.

What Needs to Change

Maintain a low threshold for testing blood lead levels in patients with anaemia and/or abdominal pain who report chronic self-medication with Ayurvedic products. ²

The DCGI must develop specific surveillance frameworks for opioid-containing preparations marketed under the Ayurvedic banner. Mandatory heavy metal testing before market authorisation, strict OTC restrictions, and online sale prohibitions for products containing scheduled substances.

The problem is not classical Ayurveda alone, but the collapse of supervision, standardisation, and accountability in the OTC commercial market.

For Patients and Families, “Ayurvedic hai toh safe hai” is not a medical fact. It is a cultural assumption, and in some cases, a dangerous one. No preparation should be self-prescribed based solely on its label.

Conclusion

Charaka wrote that nothing in the world is inherently medicine or poison. It depends entirely on how it is used, by whom, and with what knowledge. Ayurveda, at its classical best, was always a system of deep knowledge held by trained physicians. The tragedy of Kamini is not that Ayurveda is dangerous. It is that an ancient system built on careful, physician-supervised use has been reduced to an unlabelled pellet sold at a grocery counter.

The true prevalence of Kamini-related toxicity is unknown. Published literature likely captures only a fraction of cases due to underreporting, limited toxicology testing, social stigma around substance use, and low clinician awareness.

All that glitters is not always gold. Sometimes, it is lead.
