Persimmon Calyx, derived from the calyx of the persimmon fruit (Diospyros kaki), is a valued ingredient in traditional Chinese medicine.

Persimmon Calyx is distinguished by its high tannin content, which contributes to its astringent and anti-inflammatory properties. Flavonoids present in the calyx also provide antioxidant benefits, helping to neutralize free radicals in the body. The calyx is usually dark brown or reddish-brown when dried and has a slightly bitter taste. Its quality is assessed based on color, dryness, and the absence of impurities. High-quality Persimmon Calyx should be free from mold and have a consistent texture.

B2B Procurement Guide

For B2B buyers, sourcing high-quality Persimmon Calyx involves verifying the supplier's credentials and ensuring compliance with industry standards. It is advisable to request lab test reports for contaminants and active compound levels. Prices vary based on quality, with premium-grade calyxes commanding higher rates. Buyers should also consider the drying method used, as sun-dried calyxes may retain more bioactive compounds compared to machine-dried ones. Establishing long-term relationships with trusted suppliers can ensure consistent quality and supply.
