Shankhpushpi Extract: A Complete Buyer's Guide

The Problem in One Sentence

The Four Species

Three plant families. Different chemistry. Same name on the invoice.

This Is Not Fraud

Worth dwelling on, because it changes how you should handle it.

The divergence reflects genuine regional variation in classical usage going back centuries, with different Ayurvedic authorities favouring different plants. A trader in one region supplying Evolvulus alsinoides against a shankhpushpi order is not cheating you — they are supplying what the word means where they work.

Which means the usual anti-adulteration instincts are aimed at the wrong target. You are not trying to catch a bad actor. You are trying to remove an ambiguity that no amount of supplier trust can resolve, because both parties can be honest and still disagree about what was ordered.

The Fix Is One Line

Specify the binomial. Not "shankhpushpi". Not "shankhpushpi (whole plant)". The Latin name:

• Convolvulus pluricaulis Choisy — what we supply as standard;
• or whichever species your formulation was actually developed on.

Then require it to be confirmed analytically rather than declared, with the other species named as excluded. Our guide to species verification covers how.

Which Species Do You Actually Need?

An awkward question if your product already exists, and worth asking anyway.

If your formulation was developed years ago on material bought under the vernacular name, you may not know which species it was built on. Options:

1. Ask your incumbent supplier for the binomial, confirmed analytically;
2. Have retained material profiled against reference standards for each candidate;
3. If your claim substantiation rests on published studies, read those studies for the binomial they used and match the material to it.

That last point is the one most often skipped. Literature attributed to "shankhpushpi" spans all four plants, so a dossier citing a study on one species while the product contains another has a gap in it that nobody has noticed yet.

Switching Supplier Is a Species Risk

The most common way this bites: a buyer switches supplier on price, gets material that meets every line of a vernacular-name specification, and finds the product behaves differently.

Nothing on either certificate explains it, because the certificates were never asked which plant was in the drum.

The Rest of the Specification

Once the species is settled, shankhpushpi is a straightforward whole-herb extract:

• Part: whole plant — the classical part for this botanical, and it should be declared;
• Standardisation: native ratio (10:1, 20:1) with a flavonoid and scopoletin profile by HPLC. No single compound has become the accepted commercial marker, and a supplier presenting one as though it were an industry standard is overstating the position;
• Foreign organic matter: a real control on a small herb harvested from mixed ground vegetation;
• Acid-insoluble ash: expect a slightly higher limit than on a root or seed extract — 2.5% rather than 2%. That reflects ground-level harvesting honestly rather than indicating a lower standard.

Regulatory Note

A product whose declared ingredient is a vernacular name has not declared a botanical. In markets with ingredient-declaration requirements that is a genuine gap, and for EU-bound product a novel food determination may differ by species — one more reason the Latin name has to be on the paperwork rather than in an email.

What to Require

1. Binomial on the specification and the certificate — not the vernacular name;
2. Species confirmed by HPLC against named reference material;
3. Excluded species named — E. alsinoides, C. ternatea, C. decussata;
4. Whole-plant declaration;
5. Extraction ratio declared;
6. Foreign organic matter NMT 2%;
7. Acid-insoluble ash NMT 2.5%;
8. Heavy metals by ICP-MS, aflatoxins, full microbiological panel.

SV Botanica supplies Convolvulus pluricaulis from India against all of the above, and will quote an alternative species by binomial where that is genuinely what your formulation needs. Request a quotation or sample.
