Measured use of goji berries is well indicated as a health tonic for the aging. This is just as obviously indicated by the usage by noted long lived individuals as well. Too much may be well too much but a daily serving should work well.
This sort of spells out the science. i particularly note that it counteracts physical stress and thus wear and tear. i think that this observation may be somewhat unique as i know of no other claim comparing to that claim except resting. It may be important.
I think that i will add goji berries to my craisin and raisin mix. It looks good.
Wolfberry leaves are commonly used to prepare tea and wolfberry root bark is used in traditional Chinese medicine to treat inflammatory skin diseases.
According to a test-tube study, most polysaccharides from wolfberry were found to be anti-oxidative.  Published studies also suggest the possible health benefits of wolfberry for cardiovascular and inflammatory diseases, macular degeneration, glaucoma, and cancers. [A]
Alzheimer's Disease and GlaucomaRecently, laboratory has demonstrated wolfberry's neuroprotective effects to counter neuronal loss inneurodegenerative diseases. 
Polysaccharides extracted from wolfberry was able to protect neurons against beta-amyloid peptide toxicity in neuronal cell cultures, and retinal ganglion cells in an experimental model of glaucoma. 
Thus, it is reasonable to believe that wolfberry extract or its juice or tea may benefit people at risk of certain neuronal diseases. Fatigue Researchers have even isolated the active component of polysaccharide which can attenuate stress kinases and pro-apoptotic signaling pathways. 
In a 30-day exhaustive exercise program, wolfberry polysaccharides administration significantly increased glycogen level and anti-oxidant enzyme activities, and decreased malondialdehyde (MDA) level and creatine kinase activities in rats. Thus, wolfberry was able to reduce the oxidative stress in rats during exhaustive exercise. 
While, a randomized, double-blind, placebo-controlled, 14-days clinical trial of 34 subjects showed that wolfberry juice reduced fatigue and stress and improved regularity of gastrointestinal function.
Thus, wolfberry extracts including its juice may benefit people under constant stress. Cancer and Infection bnAglucopyranoside and phenolic amides isolated from wolfberry rook bark are found to have activities against pathogenic bacteria and fungi in vitro studies. [A] Wolfberry polysaccharide was shown in vitro to inhibit the growth of human leukemia HL-60 cells. 
A study of 79 advanced cancer patient s demonstrated that Wolfberry polysaccharides could enhance the anti-cancer effect of a chemotherapy on patients suffered from malignant melanoma, renal cell carcinoma, colorectal carcinoma, lung cancer, nasopharyngeal carcinoma, malignant hydrothorax.
Prolonged large intake of wolfberry tea has been reported to increase bleeding. An in vitro study suggests that it may interact with warfarin.  Atropine, a toxic alkaloid, is also found in wolfberry fruit, but its normal concentration in the berries is far below the toxic level. [A] If you are on medicine, you must consult with your doctor about the side effects of wolfberry and the potential interaction, before taking any wolfberry products including goji juice.
