What Are the Medicinal Uses of the Rosy Periwinkle?

Vinca contains more than 70 kinds of alkaloids, which is a natural medicine to prevent and cure cancer. Among them, vinblastine and vincristine have certain effects on the treatment of lung cancer and other malignant miracle tumors, lymphosarcoma, and childhood acute leukemia, etc., and are the most widely used anti-cancer plant medicine sources in the world. Peace vinca is a variety of vinca.

Perennial herb

Like warm, slightly dry and sunny environment. The suitable growth temperature is from 18 to 24 ° C from March to July, from 13 to 18 ° C from September to March, and the temperature in winter is not less than 10 ° C. Avoid moisture and waterlogging. Do not water the pot soil too much. Excessive humidity affects growth and development. Especially for indoor winter plants, watering should be strictly controlled, and drying is better, otherwise it is extremely susceptible to freezing. Open field cultivation, midsummer

Origin

Seedlings were transplanted into 10 cm pots with 3 pairs of true leaves, 3 plants per pot. When the seedlings are 7-8 cm tall, topping is done once, and then topping is done twice to promote more germination and branching and more flowering. Fertilize once every half month during growth period or use potted fertilizer. Potted plants or flower beds are planted out of the basin, flowering from late May to early November, up to more than 5 months. Residual flowers are removed at any time during the flowering period, so as to prevent mold from affecting the growth and ornamental value of the residual flowers. From August to October, the harvesting period of the vinca flowers should be harvested as soon as possible to avoid seed loss.
In normal management, you must also pay attention to ensure that sufficient light is given to the plant. If it is in the shade for a long time, insufficient light will make the leaves yellow. If the soil is partially alkaline and compacted, with poor water infiltration and poor air permeability, the plants will also grow poorly, and the leaves will be yellow and not flowering. In winter, you should move into the room, keep the room temperature above 5 degrees, and control watering. It is better to dry the potting soil. If the room temperature is maintained at about 15-20 degrees, sustainable flowering will continue. After spring, it can be moved to outdoor management. Periwinkle is generally cultivated every two years.
The vinca fruit ripening period is from September to October. The fruit has continuously matured, and the husk is easy to crack, so it must be collected in time. Vinca multiplication is used for sowing. Sowing is generally carried out in early April and can be done in open or pot. In addition, you can also take cuttings from the old plants in spring to propagate, and topping after survival, to promote more branching.

In November 2012, Dr. Hou Shixiang, Distinguished Professor of the Yangtze River Scholars of Shanghai Jiaotong University and the leading talent in Shanghai, led the team to solve the problem that it has been difficult to achieve genetic transformation and regeneration of vinca flowers for decades. Increased the content of cancer treatment substances in vinca. ^[1]

Hou Shixiang's team over-expressed transcriptional regulatory factors and key enzymes in the process of vinca alkaloid synthesis through metabolic technology, which greatly increased the content of vinca flowers that can treat cancer.
