Properly harvesting Chinese medicinal materials is very important to ensure the quality of medicinal materials. The general collection principles of commonly used Chinese medicinal materials are now briefly introduced to everyone. The roots of 1 root and rhizome medicinal herbs are plant storage organs. When the local plants start to grow, they tend to consume nutrients stored in the roots. Therefore, it is generally recommended that roots and rhizomes should be harvested in their dormant stages, that is, harvested in autumn and winter. . For example, yellow is harvested at the end of autumn or winter, when the texture is firm, and the dryness is also sufficient. However, in the spring, after the growth of the above-ground parts, the harvested pines were soaked. After dried, their characters dried up like firewood, and they were not silty and they could not be used as medicine. However, there are exceptions, such as the bright spring dwarf codonopsis, Taizishen harvested better in the summer, Yan Husuo (Yuan Hu) is a plant in early spring, it should be excavated in the ground after the beginning of summer parts withered. 2 Leaves and whole herbs should be harvested when the ground herbs of the Chinese herbal medicine grow most vigorously or when the flower buds are to be opened, or when the flowers are in bloom, and the fruits are not ripe yet. For example, the leaves of Artemisia are harvested before flowering. A few leafy herbs are harvested in autumn and winter, such as mulberry leaves. All artemisia annua and mint were harvested when the stems and leaves grew vigorously. Motherwort, Nepeta, and aromatic needs are harvested at the time of flowering. The whole grass is generally cut off from the ground, and a few roots are picked up, and the whole plant is medicinal, such as Po Gong Gong and Asarum. Stemwood medicinal herbs are generally harvested in autumn and winter, such as Guanshuitong, Daedixou, Lonicera japonicum, Shouwutong and so on. Some wood herbs are available throughout the year, such as hematoxylin, dangxiang, agarwood and so on. 4 The skin herbs are generally harvested at the end of spring and early summer. At this time, bark nutrients and liquid juice increase, the formation of cell division is faster, the skin and wood are easy to peel, the wound is more likely to heal, such as Cork, Magnolia, Qinpi. A few skin types of herbs are taken in autumn and winter, such as Chuanxiongpi, cinnamon, etc. The active ingredients in the skin are higher. 5 Flowers and herbs should generally be harvested when flowers are in season. It should not be harvested when the flower is fully opened, but must not be harvested when the flower decays. Because the latter two conditions not only affect the medicinal properties, color, and odor, but more importantly, the content of the medicinal components will also be significantly reduced. Such as honeysuckle, magnolia flowers, cloves, glutinous rice, etc. should be harvested when the flowers are in season. Red flowers, golden flowers, etc. should be harvested when the flowers are just opened. Chrysanthemums are harvested when the flowers are in full bloom. For plants with a long flowering period and flowers, they should be picked in batches to ensure the quality of the herbs. Individuals such as pine pollen and Puhuang need to grasp the pollen collection time, otherwise they will fall off naturally and affect the yield. 6 Fruits and seeds Herbs are generally harvested when the fruit is nearing maturity or maturity, such as mirrows, medlars, and hawthorns; some are picked after the fruit has matured after undergoing frost discoloration, such as Chuanxiongzi by the yellowing of the frost, hawthorn Pick when the cream turns red. Some specialize in immature fruits, such as solid, green and so on. If the actual maturation period is inconsistent, it can be used with harvesting. If it is harvested too early, the meat will be thin. If it is too late, the pulp will be loose and affect the quality and yield, such as papaya. Seed herbs must be harvested when the fruit is fully mature, such as yamu, cassia, and mustard seeds. 7 Animal medicines vary according to their types and medicinal sites. In general, most of the animal and insect medicines are in the spring, summer and autumn seasons, and they are captured during their active periods, such as spotting, pupa, glutinous rice cakes, whole oysters, and snakes. Some egg-sheathed drugs were collected before mid-March and outdated eggs hatched adults. The use of adult insects should be captured during their active period; winged insects should be caught in the morning when the dew is not dry; pilose antler should be sawn from mid-May to late July, and ossification is an obsolete corner; Niuhuang and Ma Bao stones. Herbs should be taken during slaughter. Amphibians, such as earthworms, are trapped when they enter hibernation at the end of the fall. They cannot be used for explosives or electricity. Catfish fishing and exhausting chickens to get eggs should be prohibited. China Agricultural Network Editor
