Blood peach originated in the west of Tongbai County, Nanyang, and is one of the oldest peach varieties. According to Tongbai county records, Tongbai county has planted Chinese blood peaches for more than 2000 years. It is divided into three stages: early, middle and late ripening. The maturity period is only 15-20 days, so it is not easy to store. Chinese blood peach color is bright, more than two-thirds of the peel surface is red, and the pulp is red or purple. The meat is hard, crisp and sweet, and the soluble sugar is as high as 10. 1 1%. After ripening, the pulp and stone are completely separated, and the pulp and juice are blood.

Cinnabar has the effects of clearing away heart fire, calming the nerves and detoxifying, and can be used to treat palpitation, insomnia, dreaminess and anxiety.

Cinnabar is a natural mineral Chinese medicine. Its chemical composition is mainly mercury sulfide (HgS). China Pharmacopoeia (2005 edition) stipulates that the content of mercury sulfide in cinnabar shall not be less than 96%. In addition, cinnabar also contains 25 kinds of trace elements such as lead, barium, magnesium, iron, zinc and manganese.

Cinnabar, as a representative drug for clearing away the heart, calming the nerves and detoxifying, has a history of thousands of years and is used to treat palpitation, insomnia, dreaminess and anxiety. The statistical results of prescriptions containing cinnabar collected from ancient prescriptions and China Pharmacopoeia show that the frequency of drug use is generally 10%, and the highest can reach 30%. Both Shennong's Herbal Classic and Compendium of Materia Medica list cinnabar as the top grade.

In recent years, due to improper use of cinnabar, its toxicity has attracted more and more attention. China Pharmacopoeia 1995 reduced the daily dosage of cinnabar from 0.3 ~ 1.5g to 0.1~ 0.5g; The daily dose is used in the 2000 edition and the 2005 edition of Pharmacopoeia. In addition, cinnabar as a mercury preparation, the content of heavy metals (total mercury) exceeds the standard, which limits the export of Chinese patent medicines containing cinnabar. The dispute between "non-toxic" and "toxic" of cinnabar has developed into "suitable for use" and "forbidden". Some people even questioned the necessity of cinnabar in the prescription, while others thought that cinnabar should be eliminated as an internal medicine and only kept for external use, or that the effective component of cinnabar is soluble mercury, and HgS should be removed for medicine.

First, the information of heart K.

Red heart K is the rose eggplant mentioned in Lingnan Agricultural Journal, and it is also related to its fruit being as red as a rose. Red heart K is also called mountain eggplant in Guangzhou. It is strange that the word "eggplant" is easily associated with solanaceae plants, such as Solanum spinosum and Solanum nigrum, but the K of the heart has nothing to do with solanaceae plants, and the kidney-shaped seeds have no characteristics of solanaceae plants. Features: Although it can be two meters long, Roselle is an erect herb with five hairs and lavender stems in Coming and Going. There are two kinds of strange leaves: the upper leaves of the plant are deeply split into palms with three lanceolate lobes, and the edges of the lobes are serrated, while the lower leaves of the plant are undivided and oval; The leaves are hairless on both sides and have 3 ~ 5 main veins; Petioles are long and short, up to 8 cm long, only 2 cm short, and there are sparse hairs on the petiole.
