Whether the medicine is effective or not mainly depends on the medicinal materials; if the medicinal materials are well selected but the effect still cannot be achieved, then there is a problem with the production process. Lei Gong Teng Wind-Dampness Black Plaster strictly follows the principle of sufficient medication, and each patch uses dozens of animal and plant ingredients. From raw materials to production, to storage, continuous improvements and enhancements are made so that every box purchased by consumers is of superior quality, significantly effective, and effective with just one patch.
Material Selection: Authorized Limited Harvesting. Lei Gong Teng Wind-Dampness Black Plaster is carefully formulated from dozens of animal and plant medicines such as Psoralea corylifolia, Gastrodia elata, Dioscorea nipponica, Eupolyphaga sinensis, Aconitum carmichaelii, Paeonia rubra, Angelica sinensis, Buthus martensii Karsch, Herba Scolopendrae, Zamenis stejnegeri, Drynaria fortunei, Carthamus tinctorius, Strychnos nux-vomica, Cervi Cornu Pantotrichum, Epimedium brevicornum, and Lycium barbarum, among others. Many components and combinations are protected by relevant national departments, authorized for limited harvesting. The selection of Lei Gong Teng is extremely meticulous: "Cold takes root, heat takes leaf, sunny weather takes flower and fruit, rainy weather takes the whole plant." This means that in winter, the medicinal properties of plants are mostly stored in the roots, making it suitable for root-based medication; in summer, which is the vigorous growth season for plants, the medicinal properties are mostly in the leaves, making this the most effective time to harvest leaves for medication. Sunny weather is suitable for picking the flowers and fruits of medicinal plants, while wind-dampness plants require harvesting the entire plant during rainy seasons.
In terms of ointment-making craftsmanship, Lei Gong Teng continues to use ancient methods passed down for a thousand years. It takes 3 pounds of dried herbs to make one patch of ointment. For periarthritis of the shoulder, each batch of ointment undergoes "three dryings, three boilings, and three immersions," taking more than two months in total.
Three Drying Processes: First, the herbs are sun-dried, "removing coarse water, timing should not be too long"; then they are slowly air-dried, and finally oven-dried, "promoting medicinal properties, preserving essence."
Three Boilings: This involves adding various ground Chinese herbal adhesives at different temperatures and heat levels, boiling them into a glossy black soft ointment.
Three Soakings!: This involves placing the boiled ointment into different solutions, "enhancing medicinal effects, removing fire toxicity, improving storability." The purpose of the three soakings is to enhance the optimal effects of the medicine, prevent allergic reactions to some drugs on the skin, and extend the preservation time of the medicine's efficacy.
