Fresh Egg Yolk

Traditional Use

Primary Actions

• Nourishes Yin and moistens dryness - Ji Zi Huang is used when prolonged illness or febrile damage has depleted fluids and left vexation, dryness, or weakness.
• Nourishes blood and extinguishes internal wind - classical use includes tremor, spasm, or agitation when severe Yin-Blood depletion fails to anchor the sinews and spirit.
• Harmonizes the middle and settles deficiency-type nausea or vomiting - it is an animal-food medicinal used more as a restorative adjunct than as a standard dried herb.
• Gently clears deficiency heat and calms insomnia or restlessness in Heart-Kidney Yin deficiency.

Secondary Actions

• As a food-derived animal medicine, Ji Zi Huang is usually added late or prepared gently to preserve its nourishing and Yin-restoring quality.
• Traditional clinicians often prefer high-quality fresh yolks, especially in formulas for severe depletion and post-febrile dryness.
