Rou Cong Rong is a hardy perennial that lives mostly in dry areas and deserts. It is sometimes referred to as the “Ginseng of the desert.” This title refers to its ability to act as a tonic for the body. In particular, it strengthens Kidney Yang. In addition to being sweet and warm, its salty nature has an affinity to the Kidney meridian. Rou Cong Rong is primarily used to treat Kidney deficiency with symptoms such as impotence, infertility, premature ejaculation, spermatorrhea, urinary incontinence, and excessive uterine bleeding. The heavy and cloying nature of the herb also moistens the intestines and helps ease constipation, especially senile constipation.
In a recent study, chemical analysis of Rou Cong Rong demonstrated that it has antioxidant, anti-aging, and neuroprotective qualities. This is because the plant contains volatile oils, non-volatile phenylethanoid glycosides (PhGs), alditols, lignans, iridoids, oligosaccharides, and polysaccharides. The study revealed that it’s the PhGs in Rou Cong Rong that offer neuroprotection and antioxidation. It’s also the chemical responsible for helping to reinforce the vital function of the Kidneys. The polysaccharides improve overall immune function. Galactitol and oligosaccharides are the chemicals that aid in constipation relief.
