A far-infrared neck, shoulder, and back pain patch and its preparation method

Abstract

This invention discloses a far-infrared neck, shoulder, and lower back pain patch and its preparation method. The patch is composed of raw strychnos nux-vomica, raw aconite root, raw aconitum carmichaelii, raw arisaema heterophyllum, raw pinellia ternata, datura stramonium, safflower, notoginseng, frankincense, myrrh, cinnamon, kudzu root, corydalis rhizome, salvia miltiorrhiza, achyranthes bidentata, centipede, pangolin scales, Sichuan pepper, safflower, peach kernel, raw rhubarb, ephedra, cibotium barometz, parasitic plant, ground beetle, clematis chinensis, cinnamon twig, red peony root, leech, mulberry twig, acorus tatarinowii, Sichuan pepper, white pepper, and senna leaves. Made from raw materials such as dragon's blood, camphor, borneol, azone, and far-infrared ceramic powder, this invention eliminates heavy metal toxicity by not adding red lead, resulting in low toxicity and low allergenicity. The invention solves the problems of easy destruction of effective ingredients, short-lasting efficacy, and poor process stability in traditional plasters by using the residue from stepwise alcohol extraction of medicinal materials, low-temperature pulverization of resinous medicinal materials, and dispersing them together with far-infrared ceramic powder and transdermal penetration enhancers in a hot melt adhesive matrix.
