Our story
We are a specialist Pueraria mirifica store, made in Thailand by our manufacturing partner. The factory knew this plant for decades. This store exists so you can know it too, without the hype.
“For years we made Pueraria products for other people’s labels. Then we read what those labels promised, and decided the plant deserved a better introduction.”
White Kwao Krua grows wild in the deciduous forests of northern Thailand. For generations it was dried, ground and taken in small amounts by women who wanted to feel more like themselves as they aged.
The knowledge was real but loose: no doses, no standards, and no way to tell a strong root from a weak one. That gap is where our story starts.
St.Herb began as a Thai herbal manufacturer and has worked with Pueraria mirifica for more than thirty years. The team learned which roots carry the most miroestrol, when to harvest them, and how to extract without losing what matters.
For most of that time the work went into other brands’ bottles. Good product, told badly, by people who had never seen the farm.
Online, Pueraria mirifica is usually sold as a miracle with no concentration on the label and nobody to ask. We wanted the opposite: one plant, every batch assayed, and a person who has read the assay answering your message.
Narrowing to a single botanical cost us range. It gave us depth, and depth is what people asking about their hormones and skin actually need.
Today every product traces back to a harvest block, an extraction run and a lab reading. Type the lot number on any product page and you see the result for that exact batch.
We still work the same way St.Herb always has. We just show you more of it.
Two names, one process
You buy from a small specialist team. Behind that team is the full farm, lab and factory of St.Herb. Here is who does what.
Own plantation, GMP extraction and formulation, lab assays for every batch.
Routines, consults in English and Thai, honest guidance on what to expect and when.
One chain of responsibility, from seed to your door. No resellers in between.
