Because of its diuretic and anti-swelling effects and its ability to clear lung heat, it used to be used as a medicine to stop coughing, calm asthma, expectorant, anti-inflammatory, anti-bacterial, clear heat, reduce swelling, and lower blood pressure. It was later discovered that the aristolochic acid contained in Aristolochia has strong nephrotoxicity, leading to urinary tract epithelial cell carcinoma, bladder cancer, and liver cancer, and is now rarely used. However, there are still some herbal preparations that contain it, so you should pay attention to the drug ingredients and try to avoid using it. Alcoholic beverages, pickles, bacon and preserved meats. Any drink containing alcohol can cause damage to the liver, and there is no such thing as a glass of wine a day for the liver, of which liquor is the most serious. Pickles, bacon, bacon contain nitrosamines and other carcinogenic substances, and when ingested with wine, the harm to the liver increases exponentially, and increases the risk of liver cancer, so eat less and try not to eat. Eat more broccoli, oranges, kiwi, because these are rich in vitamin C, which has antioxidant effects and can inhibit the synthesis of nitrosamines. Moldy food and chopsticks.

Usually we have to choose this more permeable chopsticks basket, keep it dry, chopsticks upside down on the basket, chopsticks basket try not to place it on top of the sink, it is easy to get wet, and also the lower part of the chopsticks basket should be cleaned frequently. Chopsticks for home use are generally recommended to be replaced once every 3-6 months, and when cleaning, you should not just pay attention to the head, as there are more germs in this part of the handheld area, which should also be cleaned.
