Euphorbia helioscopia is a common Chinese medicinal material, and its picking time is usually in winter. This is because the active ingredients of the lacquer are mainly concentrated in the root. In winter, the root of the lacquer will gradually stop growing, and the nutrients will gradually gather to the root, making the efficacy of the lacquer more intense.
In addition, in winter, the temperature of Sanjiu is low, the growth rate of plants slows down, the roots of Euphorbia are not vulnerable to injury and infection, and the quality of the picked medicinal materials is better.
Therefore, picking the Euphorbia helioscopia in three or nine days can not only ensure the intensity of the efficacy and the quality of the medicinal materials, but also avoid the damage and infection to the plants, which is a more appropriate picking time.
