During menstruation, you can drink silver fungus and red dates soup, which is good for your body. It is a good idea to eat red dates to replenish iron and blood during menstruation. If the fungus is frozen in the refrigerator, it is advisable not to eat it, as it can cause stomach pain during menstruation. If it’s overnight, it’s best not to eat it, as the nutrients will be destroyed if the fungus is left for too long.
