Goji Juice Anyone?

I have been hearing a lot about the "wonders" of goji juice and I want my sister to give it a try. You see, she was only in her 20s when she was first diagnosed with primary hypertension and she has been taking "synthetic drugs" to regulate her blood pressure since then. But as we all know, synthetic drugs has adverse effects to our body so I am helping my sister find an all-natural alternative and I think this goji berry is the answer. What do you think?
