Frequently Asked Questions
Are your herbs authentic? +
Yes. We source directly from legendary Dao-Di (道地) growing regions — Ningxia for goji, Minxian for dang gui, Wenshan for san qi, and so on. Every batch is lab-tested for purity, potency, heavy metals, and pesticides.
What is blockchain provenance? +
Each herb batch generates an integrity hash that is recorded on Polygon. This creates a permanent, tamper-proof record of origin and batch, so you can verify authenticity on-chain rather than trust a label alone.
How do I claim a free NFT? +
Purchase a herb, connect your MetaMask or EIP-1193 wallet on our /wallet page, then visit /nft and click "Claim". The Heritage NFT is minted to your wallet free of charge (platform covers Polygon gas).
Do NFTs cost money? +
No. Heritage NFTs are free digital credentials. The platform pays Polygon gas (a fraction of a cent per mint). NFTs are collectibles, not securities, and carry no investment promise.
How long does shipping take? +
Most orders ship within 1–3 business days. International delivery typically takes 7–14 business days to North America and Europe, 5–10 days within Asia-Pacific.
Do you ship to my country? +
We ship to over 80 countries. If your country is not listed at checkout, contact us and we may still be able to arrange delivery.
Are these products FDA-approved? +
Our herbs are sold as dietary supplements and food-grade botanicals, not drugs. They are not intended to diagnose, treat, cure, or prevent any disease. Consult a healthcare professional before use.
Can I return opened products? +
For safety and hygiene, opened herbs cannot be returned. Unopened, sealed items may be returned within 30 days. See our Returns page for details.
