I think there are two points to pay attention to: 1, buy rose varieties with medicinal value; 2. Buy varieties with low benzene content.

Not all varieties of roses have medicinal value. The Luzhou-flavor red rose in China is a good medicinal variety, and the double-petal red rose belongs to this variety. This variety is available in Li Tianxia, Rose Beauty, Taobao shop. Roses all contain benzene, and the low content is an excellent food. At present, the benzene content of French pink roses, Bulgarian roses, Damascus roses and other varieties of roses is higher than that of petal roses, so if well-made, edible roses are still the best varieties in China.

Roses, red dates and Chinese wolfberry are all good things that can be eaten at ordinary times.
