The worms were spiritual parasites which caused overindulgence leading to complex diseases that did not respond to normal medicine and needed to be treated by fasting (Bigu), meditation (Neidan) and medicines (Waidan).

Notes:

Shatavari (A. racemosus) has very similar properties to A. conchinensis and is known in Chinese Zhang Ci Tian Men Dong (長刺天門冬, Long Spine Heavenly Winter's Gate) and so been included in this entry. Clinically it may be seen as an Indian variant of the same herb whose Vata and Pitta reducing, Kapha enhancing properties can be seen as similar to the Chinese Heat clearing and Yin nourishing effects. It is also indicated for reproductive health (Kidneys), gastrointestinal problems (Stomach) and respiratory disorders (Lung). One major difference is that Shatavari is also recommended to soothe the nervous system but this may also be attributed to an additional action resulting from nourishing Yin and clearing Fire.
