Chinese Herbs

Does anyone know where there is one in Nassau/Suffolk? My accupuncturist suggested that DH try horny goat weed to help with his numbers. She doesn't sell it and isn't sure where I can get it besides on line. I'd prefer to go someplace to get it. When I worked in the city, I was right down the block from one but I don't know of any near where I live (Massapequa Park). Thanks!
