Nighantu Paryaya System ↔ Pharmacopoeial Nomenclature

Classical Sanskrit drug names and their synonym (paryaya) sets encode real botanical, habitat, and action information, much as modern INN and binomial nomenclature aim to fix drug identity unambiguously. Where classical names diverge regionally, the mismatch has caused real harm.

IN PLAIN LANGUAGE

Classical Sanskrit names for medicinal plants often describe something true about the plant (its shape, colour, or where it grows), the way scientific binomial names try to fix a plant's identity precisely — but the same Sanskrit name can refer to different plants in different regions, which is not just a curiosity but a real source of mix-ups.

Ayurveda's naming system encodes practical knowledge (appearance, habitat, use) directly into the drug's name; modern pharmacognosy offers an unambiguous, internationally fixed identity through binomial nomenclature, pharmacopoeial monographs, and DNA barcoding — the two are complementary, not competing.

WHEN TO SEEK CARE

If a herbal product causes an unexpected reaction, ask your practitioner or pharmacist for the plant's scientific (binomial) name, not just its Sanskrit or regional name, since the same common name can denote different species in different parts of India.

🔴 REFER IMMEDIATELY

A herbal product supplied under a regionally ambiguous name (e.g. rasna) without a stated botanical species
New or worsening kidney symptoms (reduced urine output, swelling, fatigue) in a patient taking an unspecified herbal preparation
Any product from the ashtavarga group or other disputed-identity drugs supplied without disclosure that a substitute is being used
Any patient with unexplained renal impairment who has taken a herbal product whose botanical identity cannot be confirmed

Never do this

Do not accept a classical drug name alone as sufficient identification when prescribing across regions or when safety is in question — the aristolochic acid nephropathy cases arose precisely from this kind of naming ambiguity.

🟢 SUITABLE FOR ROUTINE / COLLABORATIVE CARE

AYURVEDA SCOPE

Prescribing drugs by their well-established classical name where the plant's identity in that region and tradition is unambiguous and the source is a known, tested supplier.

MODERN MEDICINE SCOPE

Establishing definitive plant identity via botanical binomial, pharmacopoeial monograph, microscopy, TLC/HPTLC fingerprinting, and DNA barcoding where identity is disputed or safety is in question.

COLLABORATIVE SCOPE

Any Ayurvedic product should ideally carry both its classical Sanskrit name and its botanical binomial, so that modern clinicians investigating a suspected reaction can identify the actual substance involved.
