I think you are talking about Ningxia Gou Ji. It bears red berries. You can find these raw berries from most Chinese stores here. I also hear that they are very good for the eyes, male fertility, etc., but better not drinking with tea leaves together. Wei shen me? Is there a problem if they are combined? They said together in the hot water they would produce a harmful substance. I don¡¯t know if there is some kind of clinic proof or not. Uh ohhhhhhhh I am toast My wife gave me this to do as she has been doing it for years. I saw others doing it also. If you happen to come up with a link on this then pleaseeeeeeee tell me. Who are "they?" Sorry, ¡°they¡± = ¡°stuff from Internet¡±. Don't worry. The Internet provides too much information, some are true, and some are not. By Gooooogle here comes a link to a Chinese site http://big5.china.com.cn/chinese/health/492425.htm. Let your SO read it and communicate back to you .
