Yuen Fung Sum Yong Trading store is located in the San Gabriel Superstore complex(at the corner of San Gabriel and Valley). As you’d suspect, it serves the Chinese-speaking community specializing in Ginseng as well as other«health» items. Ginseng is believed to deliver many benefits as a stimulant, aphrodisiac, or general cure for whatever ails you. Since it only grows in a few places in the world and … apparently … has wide variances in quality, Ginseng can range in prices dramatically. Yuen Fung Sum Yong is one of the«cheaper» sellers of Ginseng in the area, but it can still be hundreds of bucks for a small pack of «the good stuff.» This store’s main offering is Made in America Wisconsin Ginseng; however, wild Ginseng, Bird’s Nests, Shark’s Fins(allegedly), and other rare Asian medicinal and health foods are available, too. Bring someone who speaks Mandarin to negotiate … and good luck. There’s got to be a price you can both agree is fair. Parking is free for the entire shopping center.
