Ghengis Khan's Favorite Herb

It is said that while Genghis Khan was campaigning in the Central Plains, continuous rain fell for months, causing his troops to suffer from rheumatic ailments due to the unfamiliar environment. As he faced defeat in Lincheng, he became very anxious. Then, a few soldiers accidentally consumed Fu Ling and surprisingly found their ailments cured. Overjoyed, he quickly sent people to Luotian County, known for its abundant Fu Ling, and brought back large quantities. After consuming the Fu Ling, the soldiers' rheumatic conditions indeed improved. Ultimately, Genghis Khan won the battle, and the miraculous efficacy of Fu Ling in treating rheumatism became widely known.
