The root is peeled before boiling or steaming; cooking the root reduces its bitterness. ''L. rediviva'' has also been used for medicinal purposes; chewing the root was used to relieve a sore throat and has also been used to promote milk flow during
lactation Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young. The process naturally occurs with all sexually mature female mammals, although it may predate mammals. The process ...
. For gardening, ''Lewisia'' species are usually planted in

, because this mimics their natural habitat. Rockeries also provide the free drainage that lewisias need to prevent their roots rotting. They may also be planted in pots, though they need to be well drained and protected from sustained wet weather.
