1. A Botanical With Nearly a Century of Documented Traditional Use
Kwao Krua has been part of traditional Thai practice for close to a hundred years, and the plant itself is geographically singular: Pueraria mirifica, a member of the Fabaceae family, grows only in the high-altitude rainforest soils of Thailand. The root is the plant part used.
For a brand, that provenance is the story. A botanical with a defined origin, a traditional name consumers can search, and a single region of cultivation gives marketing something specific to talk about — origin, heritage and plant part — without reaching for language a regulatory reviewer will send back.
2. Traditionally Associated With Women's Health
In our catalog, Pueraria mirifica sits under Women's Health, and that is the category most finished-goods brands build around it. It is the reason the ingredient appears in adult women's daily formulas, life-stage lines and multi-botanical blends.
The important distinction for a formulator: Bio-Botanica supplies the extract and its documentation. What a finished product says about itself — and the substantiation behind it — is determined by the brand and its own regulatory review.
3. A Standardized Specification, Not a Variable Botanical
This is the difference that shows up in your batch records. Puresterol® is standardized to a minimum of 300 mcg of miroestrol per 100 g and a minimum of 20 mg of isoflavonoids per 100 g, so you are dosing against a defined specification rather than a botanical that moves lot to lot.
The figures for your specific lot are documented on the Spec Sheet/TDS and the accompanying Certificate of Analysis. Generic Pueraria mirifica material is typically supplied without that guarantee, which means the burden of characterizing it lands on your lab.
4. Patent Protection Generic Pueraria Mirifica Cannot Offer
Puresterol® is covered by U.S. Patent 7,658,955 and is the only patented, specially processed compound of Pueraria mirifica available on the market today. The patented process is what separates it from commodity Pueraria mirifica extract and powder.
For brands that need a defensible point of difference on an ingredient deck — rather than "we use Pueraria mirifica," which any competitor can also say — a named, patented, standardized material is the practical answer.
5. Two Formats: Alcohol-Free Liquid and Powdered Extract
Both formats are the same patented, standardized extract. Choosing between them is a process decision, not a potency one:
- Alcohol-Free Extract, Part ID 5529 — a liquid input for liquid supplements, shots and beverage concentrates.
- Powdered Extract, Part ID 4523 — carried on maltodextrin for a free-flowing dry input suited to capsules, tablets, stick packs, drink powders and dry blends.
Both are intended for ingestible applications: dietary supplements and food and beverage.
6. Documentation Built for Your Regulatory Review
Puresterol® is manufactured under its patented process at Bio-Botanica's FDA-inspected cGMP facility in Hauppauge, New York. Testing runs from raw-material intake through finished product in our onsite quality lab — HPLC, UPLC-MS/MS, GC/MS, LC/MS and ICP/MS — covering identity, microbial, USP and heavy-metal testing, supported by third-party laboratories.
We operate under NSF, cGMP and FSSC 22000 quality systems, and Kosher, Halal and Organic certification is available on request. Every sample ships with a Spec Sheet/TDS, a representative Certificate of Analysis and a Safety Data Sheet, so your quality and regulatory teams can evaluate the ingredient before you commit to a run.
Puresterol® is sold in bulk to formulators and brands, in pack sizes from 1 kg through 500 kg depending on format. Pricing is quoted to your volume and specification.
