A defining feature of Physalis is a large, papery husk derived from the calyx, which partly or fully encloses the fruit. [5] Many species bear edible fruit, and some species are cultivated. The typical Physalis fruit is similar to a firm tomato in texture, and like a sweet, tangy grape in flavor. [6]
Physalis species are now studied for their potential health benefits. One study done specifically on P. virginiana was intended to investigate its antibacterial potential. The overall purpose of this study was to identify the chemical compounds of P. virginiana that could be used to make antibiotics. The researchers introduced extracts from the ...
Physalins are steroidal constituents of Physalis plants which possess an unusual 13,14-seco-16,24-cyclo-steroidal ring skeleton (where the bond that is normally present between the 13 and 14 positions in other steroids is broken while a new bond between positions 16 and 24 is formed; see figure below).

The family Physaliidae is monotypic, consisting of only one genus, Physalia. [2] The genus is also monotypic, containing only P. physalis. [1] [3] There is a long history of the genus being described with multiple species, such as the Pacific man o' war (P. utriculus), however most of these species are now considered synonyms for P. physalis.

Physalis viscosa is a species of flowering plant in the nightshade family known by many common names, including starhair groundcherry, [1] stellate ground-cherry [2] and grape groundcherry in English, and arrebenta-cavalo, balãozinho, and camambú in Portuguese and Spanish (from Guaraní akamambu, «blister»).
Physalis coztomatl is a plant species in the genus Physalis. It produces edible orange-yellow fruits, but is rarely cultivated. The leaves are oval-shaped. It is native to America; the Aztecs used it medicinally. [2] It contains labdane diterpenes, and was the first species in Physalis in which they were found. [3]
