We are honoured to be transmitting an elegant, clear and powerful approach which comes from the lineage of Dr Yaron Seidman, a disciple of Huai Xuan and the founder of Hunyuan teachings. The foundational theory and the style of herbalism that we teach in our programmes stem from the Shang Han Lun as taught by Zheng Qinan, the originator of Huo Shen Pai (Fire Spirit school), himself an early disciple of Huai Xuan.
