Staghorn Sumac Suntea Infusion Lemonade! Put fresh sumac in a glass container, add cold living spring water & let it sit in the sun for several hours or more. Strain through a tight cloth or coffee filter & enjoy this citrus tea! Avoid using hot / heated water as the Vitamin C will be drastically degraded, the sun will bring it to 96 deg F quickly, which is perfect. The taste is more like lemon-aid with a tangy, citrusy flavour. In addition to the high Vitamin C, can also be used to cure bed-wetting and other urinary disorders.
