[What is elderberry extract?]

Elderberry extract comes from the fruit of the Sambucus nigra or Black Elder, a species found in Europe, Western Asia, North Africa, and North America. Called “the medicine chest of the common people,” Elder flowers, berries, leaves, bark, and roots have all been used for centuries in traditional folk medicines.Elder fruit contains vitamins A, B and C, flavonoids, tannins, carotenoids, and amino acids. Elderberry is believed to possess therapeutic uses as an anti-inflammatory, diuretic, and immuno-stimulant.

[Function]

1. As medicine raw material: It can promote the healing of gastrointestinal ulcers; It can be used for acute and chronic hepatitis and hepatitis evocable hepatomegaly, hepatocirrhosis; promote the healing of liver function.

2. As foodstuff colorant: Widely used in cakes, beverage, candy, ice cream etc..

3. As chemical raw material for daily use: Widely used in many kinds of green medicine toothpastes and cosmetics.
