Cydonium vulgaris
Also known as Quince seed, Quince seed mucilage, Quince seeds.
Quince, Cydonia oblonga, is a small deciduous tree of the rose family, native to the Caucasus and Persia and long cultivated across the Mediterranean and temperate gardens for its fragrant, hard, yellow fruit. In herbal use the seeds are the prized part: soaked in water they release a thick, glassy mucilage prized as a gentle demulcent for irritated throats, gut linings, and skin. The physiomedicalist writers of the nineteenth century regarded quince chiefly as a mild relaxant and soothing agent, useful wherever tissues were dry, hot, or irritated and needed a bland covering rather than a stimulating remedy.

Quince seed mucilage earns its place as one of the gentlest demulcents available, comparable in feel to slippery elm or marshmallow but with a cooler, more astringent edge from the small amount of tannin and pectin the seed coat also carries.

Overview. Quince, Cydonia oblonga, is a small deciduous tree of the rose family, native to the Caucasus and Persia and long cultivated across the Mediterranean and temperate gardens for its fragrant, hard, yellow fruit. In herbal use the seeds are the prized part: soaked in water they release a thick, glassy mucilage prized as a gentle demulcent for irritated throats, gut linings, and skin. The physiomedicalist writers of the nineteenth century regarded quince chiefly as a mild relaxant and soothing agent, useful wherever tissues were dry, hot, or irritated and needed a bland covering rather than a stimulating remedy.
Clinical Notes. Quince seed mucilage earns its place as one of the gentlest demulcents available, comparable in feel to slippery elm or marshmallow but with a cooler, more astringent edge from the small amount of tannin and pectin the seed coat also carries.
Properties and Uses. The seeds of quince contain a large quantity of a peculiar and very pleasant mucilage, which most abounds in their leathery covering. They yield this property to boiling water, and a drachm of the seeds is sufficient to make a pint of water quite mucilaginous.
Properties and Uses. The roots of these plants are the medicinal part, and were introduced to practice by Dr. S. Thomson-with whom they formed a leading remedy. They are nearly pure relaxants, with not enough stimulation to be available.
