Golden Tassel Seed Slice (Rosa laevigata), known in Traditional Chinese Medicine as Jin Ying Zi (金樱子), is the sliced fruit of the Cherokee rose plant, traditionally used to stabilize and bind the essence, stop chronic leakage, and support kidney and bladder health. These carefully prepared slices retain the fruit’s naturally tough skin and fibrous interior, making them ideal for slow simmering in tonic decoctions. In TCM, Jin Ying Zi is primarily used to secure the lower burner, addressing issues such as urinary frequency, incontinence, premature ejaculation, and chronic diarrhea—especially when linked to deficiency of the kidney and spleen qi or yang. While it is astringent in nature, it is considered gentle and non-drying, often included in formulas where consolidation is needed without compromising fluid balance. Beyond its use in traditional formulas, Rosa laevigata is also noted for its antioxidant content and natural tannins, which contribute to its toning and tissue-tightening effects, particularly in cases of weakness or leakage. When decocted, Golden Tassel Seed Slice produces a mild, astringent tea with earthy undertones, and is often combined with herbs like Shan Zhu Yu (Cornus), Sang Piao Xiao (Mantis Egg Case), or Tu Si Zi (Cuscuta) in kidney-essence-conserving formulas. Each batch of Golden Tassel Seed Slice (Rosa laevigata) is carefully sliced and dried to preserve its traditional energetic qualities and clean, whole-fruit integrity. Whether used in tonic blends, formulas for reproductive or urinary stability, or long-cooked herbal teas, Jin Ying Zi offers a time-honored, effective way to consolidate essence, tonify deficiency, and support lower burner function.
