Schedule E(1): Medicines That Need a Vaidya's Supervision

Some classical Ayurvedic medicines contain ingredients that the law treats as potent. They are genuine, time-tested medicines with a long place in Ayurvedic practice — but they are not meant to be picked off a shelf and taken on your own judgement. Indian drug law recognises this, and so do we.

What Schedule E(1) actually is

Schedule E(1) is a list inside the Drugs and Cosmetics Rules, 1945. It names the substances in Ayurveda, Siddha and Unani that are classified as poisonous — in the pharmacological sense of being potent and dose-sensitive, not in the sense of being unfit to use.

Rule 161(2) of the same Rules says that any medicine containing one of these ingredients must carry the caution above on its label, in English and in Hindi. That line is not a disclaimer a company adds by choice. It is a statutory requirement, and it means what it says.

Why Ayurveda uses these ingredients at all

Classical Ayurveda has never avoided potent substances. It developed something more careful instead: shodhana — a defined purification process that each such material must pass through before it can enter a medicine. Vatsanabha is steeped in cow's urine or milk; Bhallataka is processed in brick powder and milk; Kupilu is boiled and the seed coat removed; mercury passes through an elaborate sequence before it becomes kajjali or rasa sindura.

This is why a Rasa Shastra medicine is not the same thing as its raw ingredient, and why the classical texts specify the dose in ratti and guanja — very small units. The safety lies in the processing, the quantity, the anupana and the duration — all four of which are clinical decisions.

Which ingredients are on the list

Of vegetable origin

Of mineral origin

Haratala, Gauripashana, Parada, Manahshila, Tuttha, Rasa Karpura, Sindura, Hingula and Girisindura. Of these, Parada is the one most often encountered, because kajjali and rasa sindura are the base of a great many classical rasaushadhis.

Of animal origin

Sarpavisha.

Two things people commonly get wrong

• Ativisha is not Vatsanabha. Aconitum heterophyllum (Ativisha, Atis) is a different species from Aconitum ferox, it is not on Schedule E(1), and it is used freely — including in children's formulations. The names look alike; the plants do not behave alike.
• Not every bhasma is Schedule E(1). Swarna, Rajat, Loha, Abhrak, Vanga, Tamra, Praval, Mukta, Shankh, Godanti and Kasis bhasmas are not on the list. They are still classical mineral preparations that a vaidya should select and dose — but the statutory Schedule E(1) caution does not apply to them, and we do not print it where it does not belong.

What this means when you buy from us

Every product on riddhishherbals.com that contains a Schedule E(1) ingredient carries this caution on its page. We stock these medicines because practising vaidyas prescribe them and patients need a genuine source. We do not recommend them for self-selection, and we would rather lose a sale than have someone take a rasaushadhi on the strength of a web search.

• Take it only if a registered Ayurvedic physician has prescribed it for you, by name.
• Take the quantity your vaidya specified — not a spoonful, not “a little more since it is natural”.
• Follow the anupana your vaidya named. With these medicines the vehicle is part of the prescription.
• Tell your vaidya about every other medicine you take, Ayurvedic or modern.
• Stop and go back to your vaidya if anything feels different.
• Not in pregnancy or while breastfeeding, and not for children, unless your vaidya has specifically said so.
• Keep them out of reach of children, in the original labelled pack.
