Therefore, according to the relationship between the five elements (summer is fire), 50% (summer is long), five internal organs (heart) and five flavors (bitterness), it is said that the heart is not eaten in summer, and bitter things can also help the heart and control the lung qi. Summer is also the season of sweating. If you sweat more, you will lose more salt. If the myocardium is short of salt, the heartbeat will be abnormal. Chinese medicine believes that at this time, it is advisable to eat more sour taste to consolidate the exterior and more salty taste to replenish the heart. "Su Wenzang's Odd Dharma Wheel" says: "The heart governs summer, the heart is bitter and slow, the heart wants to eat acid to receive it, the heart wants to eat salt to absorb it, salty to supplement it, and sweet to purge it." That is to say, Tibetan gas is soft to salty to soft.
