The lycium extract is produced by (a) adding 1-5 wt.pts. cinnamon bark, 1-5 wt.pts. zingiber, 1-5 wt.pts. jujube and 1-5 wt.pts. glycyrrhiza to 100 wt.pts. lycium, (b) adding an water of ten times the mixture, immersing the mixture in the water at 80-100 deg.C for 5-6 hrs. to extract a lycium component, cooling the lycium extract at 0-10 deg.C for 20-30 hrs., filtering and centrifugally separating the extract to obtain a supernatant, and concentrating the supernatant at 80 deg.C by the vacuum pressure-reduction concentration machine to have 40 % water content. The lycium extract is used as an additive for health foods.
