Traditional Chinese medicine has long used lyceum barbarum polysaccharide (LBP) to treat high blood sugar levels in Type 2 diabetes.
LBP is one of the chief molecules found in goji berries.
Researchers at Southeast University in Nanjing, China, studied LBP as a way of lowering blood sugar levels in Type 2 diabetes.
Their study, reported on in the journal Medical Chemistry in November 2014, included 67 people diagnosed with Type 2 diabetes.
A total of 37 diabetics were given LBP while the rest took a placebo for 3 months.
Blood sugar levels went down and HDL levels went up in the group taking LBP.
From these results it was concluded LBP might have value when used alongside proven safe and effective antidiabetic medications.
Goji berries are high in vitamin C, vitamin A, vitamins B1 and B6, iron, and fiber.

Goji berries are oval-shaped, red-orange berries from the Himalayas of China, but can be grown in a wide range of climates, including all 50 states in the United States.
To grow goji berry plants...

• pick a sunny location unless you live in a desert climate, in which case you will want to plant your seedling where it will have some shade.
  
• goji plants tolerate a soil ph between 6.
  8 and 8.
  1.
  Use a soil amender if your soil has too much clay.
  
• soak bare root plants in water for 15 minutes before planting.
  
• dig a hole with a mound in the center and place the roots outward and downward.
  Cover the roots with soil and water well.
  
• keep the soil moist.
  
• harvest when berries turn red-orange.
  
• trim all old growth, because berries only grow on new growth.
  

Goji berries are almost impossible to find in the produce department outside of China, but powdered forms are found in health food stores.
Always consult your doctor before beginning supplements.
