Amara, also known as Citrusaurantiumvar, is an evergreen shrub belonging to the genus Citrus in Rutaceae. Its branches are dim and slender, alternate leaves are leathery and oval, with white flowers in spring and summer (April-May) and rich fragrance. Its fruit is oblate, orange-red in winter and green in summer.

Generally, tortoiseshell tea is brewed with mid-range green tea. In the first year, you must prepare enough tea blanks and store them in a dry and cold environment to keep their green tea style as usual, especially to avoid mildew. Before smoking, the biscuits should be baked well, so that the old flavor will evaporate and the tea fragrance will be exposed, which is beneficial to the development of Zan-Zan aroma.

Because hawksbill flower petals are thick, aromatic oil is easy to be distributed at high temperature, so it is often heated to facilitate the volatilization of aroma and the absorption of tea blank. After the camellia is mixed, it is sent to a dryer for heating, and immediately stored around after drying.

The efficacy is to soothe the liver and stomach and regulate qi.
