Notes:

Not normally consumed but is an important component of many sexual internal alchemy longevity techniques where one's own semen is retained to prevent loss of Jing and instead redirected into the subsequent meditation practices. However, some rites have existed that involve the consumption of one's own or others' essence as an alchemical substance to artificially supplement their own Jing, a practice considered wicked and harmful to most.

Li Shizhen writes: "Evil alchemists [邪術家] fool stupid maidens and mate with them. Then they drink the vaginal secretions of the girls. Or they blend their own semen with the menstrual blood of a maiden and eat it. This mixture is called Qiangong [鉛汞] (lead and mercury). They consider this a treasured drug and indulge in sex excessively, eating such a foul thing. This practice will shorten their lifespans greatly. What a stupid thing!
(Li Shizhen, 1597, trans. Luo, 2003: 4173)".
