Physalis is a tropical fruit originally from South America. Scientifically named Phisalys peruviana L., this is an invasive plant that grows spontaneously without the need for great care. The plant grows well especially on the south coast of Madeira Island. The fruit is round and has a sweet and sour taste. From the point of view of health, the fruits have antioxidant properties (preventing the formation of free radicals in the body) and anti-inflammatory properties, given the presence of physalin, pointed out as a weapon against cancer and tuberculosis in some studies. The fruits are also colloquially recommended for those who have skin diseases. They are rich in vitamins A and C and fibers that help to regulate blood sugar levels.

Physalis is widely used in jams and jellies, and is also eaten by itself.
