Peach Seed / Peach Kernel

OVERVIEW

What This Record Covers

Peach Kernel is the dried seed kernel of Prunus persica and accepted related peach sources, a fruit tree of the rose family (Rosaceae) cultivated worldwide. The medicinal material is the flat, elongated kernel removed from the hard pit, which is brown outside and pale inside, and the kernels are cleaned, dried, and often crushed before use. In trade it appears as whole kernels, crushed pieces, powders, and combined formulas, and it is a standard ingredient in blood-stasis and bowel-moving combinations. Because bitter and sweet apricot kernels and other Prunus kernels look similar, the species, the seed coat, and the presence of any bitter taste must be confirmed with the label.

IDENTIFICATION

Identification and Image Notes

Peach kernels are flat, elongated, and brown with a pale interior, and bitter and sweet kernel types, the peach species, and the presence of the seed coat affect the record. The material can be confused with apricot kernels and other Prunus seeds, so the species statement on the label is the identity record.

Images are for orientation only, not definitive species authentication; confirm species, part, source, and labeling with a qualified professional or authoritative monograph.

TRADITIONAL CONTEXT

Traditional Use in Context

Traditional records discuss Peach Kernel for blood stasis, constipation, menstrual and injury-related historical language, and it is a classic ingredient in formulas such as Tao Hong Si Wu Tang (with Safflower) for menstrual and blood-moving contexts, and in bowel-moving combinations that moisten dry stools. Classical texts describe it for menstrual pain, bruising, and dry stools, always within a pattern-based framework. The historical language does not establish efficacy for constipation or gynecological disease, and persistent abdominal pain, bleeding, or a change in bowel habit requires clinical assessment rather than self-treatment, and the kernel should not be treated as a laxative for home use.

PROCESSING CONTEXT

Raw Material, Processing, and Product Form

Kernels may be cleaned, crushed, or stir-fried, but the raw seed and the processed product remain distinct forms. Oils, extracts, and food products containing peach kernel require separate exposure and cyanogenic-compound review, because the kernels carry naturally occurring glycosides that matter at high intake.

The same name can cover a raw material, decoction piece, powder, extract, or finished product, so record the labeled form rather than assuming it; see the safety review for the questions to ask.

COMPARISON

How This Entry Differs

Compare Peach Kernel with Safflower for the seed-versus-flower pair in blood-stasis formulas, and with Rhubarb Root for the different bowel-moving end of the spectrum. Peach Kernel is the seed-based mover with a food-adjacent identity, which makes its toxicity and allergy questions distinct from the other two. As the kernel of a familiar fruit tree, it also raises the species and seed-type questions that pure root materials do not.
