Health-preserving rhizome, leaf and flower refer to the organs of plants. Green plants have six organs: roots, leaves, flowers, fruits and seeds. Roots, stems and leaves are all vegetative organs of plants, which are mainly responsible for absorbing nutrients in the process of plant growth, thus making organic matter for plant growth. Flowers, fruits and seeds are the reproductive organs of plants, which are related to plant reproduction. Fruits will be produced after flowering, and seeds will be sown when the fruits are ripe, which can be used for sowing and breeding, and some fruits also have high edible value.
