Onions have an antiviral effect

The ability to bind viral proteins reduces their multiplication and thus appears to explain this effect. Onions are used in many different ways as a household remedy. For example, sachets filled with finely chopped and lightly steamed onions can help with acute middle ear infections. Boil a whole onion. Its brew as a "tea" or thickened as a syrup with brown sugar can bring relief from coughs and colds.

Hot spices in particular, such as cayenne pepper or chili, have an antibacterial effect and strengthen the immune system.

This promotes healthy intestinal flora, which can be combined with a strong
