Hot compress sea salt
The first generation of hot sea salt: the early hot sea salt was bought by sick people in the vegetable market and used to make pickles. Because of its low mineral content, this kind of sea salt can generally be fried for three times, and the use time is about 1.5 days, and it takes about 1 10 kg a month. Disadvantages are high corrosiveness, low mineral content, easy abortion due to heavy metals such as fluorine, and relatively complicated operation. Zanthoxylum bungeanum, ginger and cinnamon need to be added to increase the absorption degree of meridians, and the added organic matter may cause the threat of secondary infection because it is perishable.
The second generation of hot compress sea salt: In order to prolong the service life, Taiwan Province bag salt field has been researched for four years, and 1998 was published. Because it can be used for 10 to 15 days, I applied for a patent. This is indigo salt sold in pharmacies, also known as halite, and of course there are many names. Drug stores are all 10 yuan a kilo. The disadvantage is that pepper is still needed to promote the absorption of meridians.
Third-generation hot compress sea salt: it came out in 2004, and it has the characteristics of high temperature and no melting, and the effective minerals are evenly muddy. The service time of sea salt for frying is extended to 1 month, and the service time of sea salt for microwave oven can reach 4 to 5 years. Later, the popular "ice and fire physiotherapy pillow" belongs to this type. The advantage is that compared with the second generation of sea salt, the gynecological treatment time is shortened to 2 years, and the previous sea salt needs about 3 years.
