The etrog citrus fruit is particularly important to Jews on Sukkot.

The 18th century botanist Charles Linnaeus gave the etrog its Latin name, citrus medica, after its remedial properties. Uzi Eli wised up to the etrog’s magic powers and set up a line of etrog-based beauty products that treat acne and premature wrinkling.

Eli describes to host Daniella Cheslow some of the yellow citron’s more legendary powers, such as curing child mutism.
