Plant Source


The sunflower (Helianthus annuus) is a perennial flowering plant that is native to North America. It is cultivated in regions as a food crop and ornamental plant. The sunflower is a symbol for energy and perfection because of its symmetry and longevity. The sprouts of this fast growing plant have the highest concentration of phytonutrients, the compounds in plants that are known for their health promoting properties.

Tara (Caesalpinia spinosa) is a small leguminous tree that is native to the Peruvian Andes and which tolerates dry climates and poor soils. Tara’s fruits are called pods and are used in traditional medicine to treat infections and to improve healing. They are very rich in hydrolysable tannins with gallic acid as the main constituent. Tannins extracted from tara are highly efficient and stable antioxidants.
