Our green tea supply chain
Camellia sinensis L.Thé vert

Pharmanager Ingredients has chosen to develop a responsible supply chain for the cultivation of green tea.

Did you know ?

An old legend has it that a Chinese emperor who was resting under a tree boiled water to purify it before drinking it. Some leaves from the tree then fell into his water. He nonetheless tasted the beverage, which he found exquisite; he could feel its benefits for his body. He was sitting under a wild tea tree. 

Where does our green tea extract come from ?


The green tea leaves used for our extract come from Mengding Moutain in Sichuan Province and Hanzhong in Shaanxi Province. These two provinces have historically been known for their green tea plantations for over 2,000 years. The climate is ideal with temperatures above 10°C and regular rainfall throughout the year (1,500 mm/year).

China is the birthplace of tea, as it was home to the very first tea plants.

Our tea leaves come from family farms and cooperatives. They are picked manually and mechanically but are sorted by hand according to their quality. Batches are selected by phytochemical analysis in order to guarantee a specific polyphenol content prior to the extraction step. Thé vert

What is the best harvest period ?


Green tea is harvested in spring and summer, from April to August. The rest of the year, tea plants are dormant to ensure a good antioxidant content for the spring harvest. champs thé vert

How is our extract unique ?

Extraction is carried out in Hunan Province. It takes place right after the harvest, to exploit all the active ingredients in tea that give it its health benefits.

We propose native extracts, that is to say that the extraction is made only with water in order to be close to the traditional use and we do not use excipients (silica or maltodextrin).

It boasts 30% polyphenols and 15% catechins without containing too much EGCG.

Benefits of green tea

Numerous health claims about green tea are awaiting a decision by the European Commission, including a dozen relating to its anti-oxidant and slimming properties as well as its effects on cognitive function and the cardiovascular system.

  • Due to their antioxidant activity, the polyphenols found in green tea help protect our cells from free radicals and thereby preserve good health. They help protect the body by strengthening its natural defences against free radicals.
  • Drinking tea contributes to the oxidation of fat. In other words, it stimulates the breakdown of lipids and thus helps weight control.

  • Traditionally used to combat mental or physical fatigue, green tea is used to improve memory and concentration and during intense physical activity.

  • Together with exercise, green tea helps maintain normal blood pressure and improve blood circulation.

The various kinds of tea

Green tea, black tea and white tea all come from the same species of tea plant. They differ in terms of the methods used to dry and ferment the leaves.
