Why can't you eat loofah in autumn?

According to Baidu Health, you can eat loofah in autumn after the solar terms in beginning of autumn and beginning of autumn. Traditional Chinese medicine believes that loofah is cool and sweet, and enters the liver and lung meridians, which has the functions of clearing away heat and resolving phlegm, cooling blood and detoxifying, relieving summer heat and relieving annoyance, dredging meridians and activating collaterals. Eating more loofah after beginning of autumn can prevent lung heat and nourish delicate lungs. The reason why beginning of autumn loofah can't be eaten is that beginning of autumn loofah is getting old, which will lead to fibrosis. It tastes hard and thick, and can't be chewed, so people generally don't choose to eat loofah after beginning of autumn, not because it is harmful to the health after eating it in beginning of autumn.
