Sugar Bush (Rhus ovata)
Sugar bush, also known as sugar sumac, is an evergreen shrub in the Anacardiaceae family. You can find this shrub growing in the chaparral region of southern California, often on south-facing slopes near 3,500 feet in elevation.
Sugar bush has a rounded appearance. Its leaves are thick and dark green – as is common for the sumac family. The branches and twigs are reddish.
Many members of the sumac family produce an irritant molecule, called urushiol. Urushiol is the culprit that causes a rash when we handle the oil of poison ivy and mango plants. There are unconfirmed reports that traces of urushiol oil exist in the sugar bush as well.
Healthy clusters of flowers, white to pink in color, appear in dense inflorescences along the ends of branches. In the spring, these flowers fade and are replaced by bright red berries.
Uses for sugar bush
The small fruits from the sugar bush can be pressed to make a tart beverage, similar to lemonade. This drink kept early southern Californians cool on hot, dry summer days in the chaparral.
The Cahuilla people of the Mojave Desert collected sugar bush berries and ate them raw. These berries were also mashed into a porridge or else dried for later use.
The Cahuilla also used Rhus ovata for medicinal purposes. They prepared an infusion of leaves and drank it as a remedy for colds. This infusion was also applied for chest pains and coughs. The use of natural plant extracts to treat colds is a common phenomena throughout history. In Central Europe, an infusion made from the black elderberry extract was used to treat the cold and flu.
The Kumeyaay people of the San Diego area prepared an infusion of sugar bush leaves and drank the concoction before childbirth to ensure an easy delivery.
