Overview

The 'Plain Questions - On the Formation of the Five Zang-Organs' states: "When a person lies down, blood returns to the liver." The Zi Wu Liu Zhu (Meridian Flow) theory states: the Chou hour (1:00-3:00 AM) is when the Liver Meridian of Foot-Jueyin commands — the time for liver blood to return to its meridian and discharge the old to receive the new. Chronic sleep deprivation prevents liver blood from being stored, continuously depleting liver yin, leading to liver-yin deficiency and deficiency-fire flaring upward: dry eyes, dizziness, irritability, dark complexion. ZhengYiKang's formula employs "nourishing yin, enriching blood; clearing liver, brightening eyes; calming heart, settling spirit."

Herb Properties & Meridian Tropism

**Chrysanthemum (Ju Hua)**: Sweet-bitter, slightly cold. Enters Lung, Liver meridians. Clears liver, brightens eyes, disperses wind-heat — purges liver meridian deficiency-fire flaring causing red, dry eyes

**Cassia Seed (Jue Ming Zi)**: Sweet-bitter-salty, slightly cold. Enters Liver, Large Intestine meridians. Clears liver, brightens eyes, moistens intestines — enters liver meridian to clear liver heat while benefiting liver yin

**Goji Berry (Gou Qi Zi)**: Sweet, neutral. Enters Liver, Kidney meridians. Nourishes liver-kidney, enriches essence, brightens eyes — replenishes liver blood to moisten both eyes

**Mulberry Leaf (Sang Ye)**: Sweet-bitter, cold. Enters Lung, Liver meridians. Disperses wind-heat, clears liver, brightens eyes — cools and moistens the liver meridian to control deficiency-fire

**Prunella (Xia Ku Cao)**: Acrid-bitter, cold. Enters Liver, Gallbladder meridians. Clears liver, drains fire, disperses masses — specifically descends liver meridian constrained fire

**Jujube Seed (Suan Zao Ren)**: Sweet-sour, neutral. Enters Liver, Gallbladder, Heart meridians. Nourishes heart, settles spirit, astringes sweat — helps yang enter yin to pacify sleep

Mechanism of Action

The liver opens into the eyes; the Liver Meridian of Foot-Jueyin "connects to the eye system" and "ascends through the forehead, meeting the Governing Vessel at the vertex." At Chou hour when the Liver meridian commands, one should "lie down so blood returns to the liver"; staying awake causes liver blood to be externally consumed rather than stored. The liver meridian traverses the eye system — insufficient liver blood means the eyes lose nourishment; the meridian ascends to the vertex — deficiency-fire flaring upward causes dizziness. The formula uses liver meridian-entering herbs as sovereign: nourishing liver yin and blood to treat the root, returning blood to the liver; clearing liver fire and dispersing constrained heat to treat the branch, preventing deficiency-fire from flaring; calming heart spirit and aiding sleep to align with the liver meridian's commanding rhythm.
