Cassia Seed (Cao Jue Ming Alias)

Traditional Use

Primary Actions

• Clears Liver Heat and brightens the eyes - Cao Jue Ming is used when red, painful, swollen, gritty, or light-sensitive eyes arise from Liver Fire, Wind-Heat affecting the eyes, or chronic visual strain with residual Heat.
• Calms rising Liver Yang and directs excess upward activity downward - the seed's descending, cooling nature makes it a classic choice for headache, dizziness, irritability, and hypertension-pattern symptoms when red eyes or Liver Heat are part of the picture.
• Moistens the Intestines and relieves Heat-type constipation - its oily seed nature softens dry stool while the bitter-salty profile drains Heat downward, especially when constipation accompanies headache, red eyes, or internal Heat.
• Gently supports Liver and Kidney Yin while draining excess Heat - unlike heavier mineral substances, Cao Jue Ming can clear and descend without being purely sedating, so it is often chosen when chronic eye strain, aging vision, or mild deficiency underlies the pattern.

Secondary Actions

• Dry-frying softens the herb's laxative effect and shifts it somewhat toward Yang-calming and eye support rather than stronger bowel-moistening.
• This alias entry preserves a common folk and trade name, but the medicinal identity here is the same Cassiae Semen drug represented more fully under herb #194, `cassia-seed-2`.

Classic Formulas

• Shi Hu Ye Guang Wan (石斛夜光丸) - classic eye formula for chronic Liver-Kidney deficiency with internal Heat, where Jue Ming Zi-class cassia seed helps brighten the eyes while the formula nourishes deeper fluids and Essence.
• Jue Ming Zi with Ju Hua (决明子配菊花) - classic tea-style pairing for red or tired eyes with headache, combining interior Liver-Fire drainage with exterior Wind-Heat clearing.
• Jue Ming Zi with Gou Teng and Xia Ku Cao - common modern-classical pairing pattern for Liver-Yang rising, headache, dizziness, hypertension, and red eyes.

Classical References

• ALIAS NOTE: Cao Jue Ming (草决明) is a long-standing alternate name for Cassiae Semen and should be treated here as the same medicinal identity as Jue Ming Zi (决明子), herb #194.
• HISTORICAL CONFUSION NOTE: several traditional and folk sources also used the name Cao Jue Ming for Qing Xiang Zi (Celosia seed), so authenticated sourcing matters; this record follows the Cassia/Senna seed identity, not Celosia.
• Me and Qi notes that Jue Ming Zi was first recorded in the Shen Nong Ben Cao Jing and remained especially associated with eye complaints, Liver Heat, descending Yang, and bowel moistening.
