Introduction to the Plant Essential Oil Museum: Essential oil has a legendary story in Yunnan: Wu Sangui did not hesitate to surrender to the Qing Dynasty in order to get Chen Yuanyuan. Wu Meicun, a poet in the late Ming and early Qing Dynasty, wrote "The six armies of the mourning army are all in peace, and they rush to the top." Anger makes beauty" an eternal poem. Chen Yuanyuan had a hidden disease of body odor. After Wu Sangui came to Kunming, he fell in love with the beautiful scenery of Cuihu Lake. For personal enjoyment, he forced the people to fill in Cuihu Lake and built his Pingxi Palace. A large number of roses and various exotic flowers were planted in the garden of the palace. The precious flowers made Chen Yuanyuan bathe with flowers every day to cover up her body odor. A specialized perfumer also prepared a balm for Chen Yuanyuan to apply to keep her youthful forever. Using essential oils today not only makes you happy physically and mentally, but also regulates your body and cares for your skin.
