Coca-Cola is a drink whose original formula was used to treat coughs and was later modified several times to become the formula for a best-selling drink. It was later inadvertently discovered to dissolve stomach stones, which are stony masses that form in the stomach after eating certain foods. In persimmons or black dates there is something called tannin, which is found in high levels in unripe persimmons. When people eat raw persimmons, they have an astringent sensation on their tongue, which is the tannin at work. Tannin in the action of stomach acid, can be combined with protein into not easily soluble in water tannin protein, precipitation in the stomach, in the stomach can be formed in the stomach persimmon stone. People who eat persimmons with a lot of stomach acid are prone to grow stomach stones. In some people, eating raw persimmons once can lead to the formation of gastric stones. In addition, eating large amounts of black dates or hawthorn on an empty stomach can cause gastric stones. The main ingredients of Coca-Cola are: carbonated water (water, carbon dioxide), sugar, phosphoric acid, spices (contains caffeine), of which the main effective for phytoliths is phosphoric acid, which can combine with monophosphorus and also with calcium. Therefore, it can effectively destroy the polymeric substances of phytoliths, so it can dissolve phytoliths. If you are diagnosed with phytoliths, you can drink 2 bottles of Coca-Cola per day and the average phytolith will dissolve in 3 to 5 days. If the phytolith is too large to be dissolved by ordinary oral intake, the phytolith can be punctured by gastroscopy and then injected with Coke. Of course, although this treatment is simple, there are certain indications, and it is not suitable for some patients because Coke can produce a lot of gas in the stomach, which can easily cause bloating and belching, such as patients with a history of ulcers and heart disease are not very adaptable, so the medication must be used under the guidance of a doctor before use.
