What are porcupine dates?
Porcupine dates (porcupine bezoar) are concretions that form naturally inside a porcupine, built up in layers from plant material the animal has eaten. Not every porcupine forms one, and not every bezoar is of usable condition, which is why supply is so limited.
What grades does Tong Xin Yuan sell?
Five, across two lines. Traditionally milled: Grade 1 Porcupine Date Powder and Premium Grade Powder. Nano extracted: Premium Nano (Concentrated Extract), Supreme Shelled Aged Bezoar King and Royal Shelled Aged Bezoar King. See grades explained.
How much do porcupine dates cost?
In 2026, from RM400 for 1 gram of Grade 1 powder up to RM42,280 for 36 grams of Supreme Shelled Aged Bezoar King. Larger weights cost less per gram — Grade 1 at 10 grams is RM1,588, about RM159 a gram. Full list on porcupine dates price.
How do I know it is genuine?
Genuine bezoar has four features that are hard to fake: irregular concentric layering, a fine dense cross-section, a bitterness that finishes sweet, and a slow even dissolve in warm water. When buying powder, traceable provenance matters more. See the seven checks.

Tong Xin Yuan trades as Xin Juan Enterprise Sdn Bhd, company number 200401020913 / 659417-D, based at Gurney Paragon, Penang, Malaysia. Proper invoices are issued, and product documentation and test reports are available on request.
Do porcupine dates treat illness?
We do not claim that. Porcupine dates are a traditional edible product, not a medicine, and do not replace medical treatment. There is published research on the constituent compounds, but it is largely cell and animal work, not proof of effect in people. If you are under treatment, speak to your doctor first.
