厚朴树种植后一般需7～8年才开花结实。现在有些药材部门收购厚朴花,这样就很难收集到厚朴种子,给厚朴生产造成了直接的威胁。为了保证生产所需的种子,我们认为厚朴花暂不宜收购为好。厚朴花作药用,历代本草均未见记载,仅见于1936年王一仁编著的《饮片参新》一书,谓本品温香 Magnolia officinalis generally takes 7 to 8 years to grow and bloom after planting. At present, some medicinal herbs departments have acquired Magnolia Flower, which makes it difficult to collect Magnolia officinalis seeds and poses a direct threat to Magnolia Production. In order to ensure the seeds needed for production, we think that Houpohua should not be acquired for the time being. The flowers of Magnolia officinalis are used medicinally, and there are no records in ancient Chinese herbal medicine. They were only found in the book “Drinks, Tablets, and Herbs” edited by Wang Yiren in 1936.
