Nutritional value: Roselle is a plant of the Malvaceae family, which is diuretic, pungent and flat, and enters the kidney meridian.
Modern research has found that Roselle has a variety of nutritional values, including vitamins A and C, protein, fat, malic acid, iron, and sodium. Nutritional analysis suggests that Roselle contains protocatechuic acid (PCA), and the extract can increase glutathione (Glutathione, GSH).
Protocatechin is a simple phenolic compound. Some research reports indicate that it has strong antioxidant capacity and can reduce bad cholesterol. However, protocatechuic acid is not unique to Roselle, and most vegetables, fruits and walnuts also contain a lot. The main physiological function of glutathione is an important antioxidant in the human body, which can scavenge free radicals and clean up the polluted environment in the human body. It is also produced by the human liver (some people think it has a whitening and spot-lightening function, which is one of the components of the whitening needle). Because the extract of Roselle contains glutathione, it is often said to be whitening. (The whitening effect of glutathione can refer to the introduction of some beauty products in the shop).
Cooking method: For making Luoshen flower tea, one or two dried calyxes is usually enough. The first bubble should be washed with hot water and then poured out. The purpose is to remove impurities and dirt. After filtering the tea residues, add rock sugar to taste, preferably with a lid. Bake for a few minutes, the tea flavor is stronger. If you don't like to drink hot tea, adjust the flavor and let it cool before putting it in the freezer. Roselle tea should be drunk after meals to help digestion. The brewed tea soup is bright and red in color, with a slightly sour entrance and smooth throat. If it is sour and slightly sweet, it is the top grade of Roselle tea.
Roselle preserves
[Ingredients] 200 grams of Roselle flowers, 200 grams of rock sugar
[Method] Take a glass container, sterilize it with boiling water first, and then air dry it. Spread a layer of rock sugar (or granulated sugar) on the bottom of the container, then stack the roselle flowers layer by layer, spreading a thin layer of rock sugar on every few layers, and then continue stacking the roselle flowers. Repeat this step several times until the roselle is completely in the jar. During this period, you can press with a spoon to increase the tightness, and finally use rock sugar to make a knot. Seal the jar and let it cool in a cool place before moving it to the refrigerator. Let it sit for about 1 day, and then it can be eaten after the candied roselle flowers are infused.
[Efficacy] Appetizing, promoting body fluids and nourishing the skin.

Special matters: Rosellle is acidic and cool. TCM reminds: Don't eat too much for stomachaches. Pregnant women with kidney disease should take it with caution. Roselle has an acidic and cool taste, so it is not suitable to eat large amounts. It is recommended not to consume more than 20 grams of Roselle per day (regardless of brewing or eating). Rosellle Flower Tea should not be drunk on an empty stomach, and should be drunk after a full stomach (Ming Pao/Registered TCM physician Ms Ip Lai Pan).
