This species is used medicinally.

This plant may be one of the many spontaneous hybrids that originate in plantations with different Yulania species grown for medicinal xinyi with Y. biondii as one of the parents. Yulania wugangensis (T. B. Chao et al.) D. L. Fu (J. Wuhan Bot. Res. 19: 198. 2001; Magnolia wugangensis T. B. Chao et al., Acta Bot. Yunnan. 21: 171. 1999) may be another hybrid from the same sort of medicinal plantation in Henan and also involving Y. biondii as one of its parents.
