There is a principle in Unification Thought that entities not only serve their own individual purpose (maintenance, reproduction, development), but also advance a larger value (for the ecosystem, humans).
This is seen in the Artemisia genus. Many of the plant components that are so vital to the survival and reproduction of the plants—leaves, flowers, volatile oils—also provide a larger value for the ecosystem and for humans. The leaves and essential oils are used medicinally, including the production of an anti-malarial compound from Artemisia annua. Various species are used for culinary purposes, with A. absinthium used in vermouth and absinthe, and A. dracunculus (tarragon) popular in French cuisine. Indeed, tarragon is one of the four fines herbes of French cooking, particularly suitable for chicken, fish, and egg dishes, and it is one of the main components of Bearnaise sauce. Although many species of Artemisia are wind-pollinated, there is evidence of insect pollination for some species (Tkach et al. 2007), with the flowers offering nectar to the insects in exchange for pollination. The attractive foliage and colorful flower-heads of some species make them desirable ornamental plants.
