Sea buckthorn tea should be brewed with cool water or water below 40 degrees. Sea buckthorn tea is made from fresh sea buckthorn leaves, which are sterilized, kneaded and baked at high temperatures in a tea-making process. It is different from ordinary traditional tea, sea buckthorn tea is rich in nutrients. It contains a variety of vitamins, free amino acids, and lipids, with up to 30 phenols and flavonoids. Water-soluble vitamins, phenols and flavonoids can only maintain their activity to the maximum extent at low temperatures, and high temperatures can oxidize and inactivate some of the nutrients. So in order to keep the nutrition of sea buckthorn tea, it is better to brew it directly with water below 40 degrees or cool water. Due to the low temperature, the brewing time can be longer. Sea buckthorn tea is rich in nutrients, which can replenish all kinds of nutrients needed by the human body, and at the same time can replenish enough water, so you can drink more appropriately. However, due to the limited dosage of its efficacy components, it cannot prevent and treat diseases. People who are allergic to sea buckthorn tea should not take it.
