Frequently Asked Questions

What is Ji Zi Huang? Are E Jiao and egg white the same?

Ji Zi Huang (鸡子黄) is the egg yolk of Gallus gallus domesticus, also called chicken egg yolk. E Jiao is sweet-neutral: supplements Blood, nourishes yin, moistens dryness and stops bleeding—it is donkey-hide glue. Egg white is sweet-cool: clears heat and resolves toxin. Write Ji Zi Huang. Use caution in phlegm-damp and Spleen vacuity with overeating.

What are the TCM properties and traditional uses of Ji Zi Huang?

Classical materia medica records Ji Zi Huang as sweet and neutral, entering the Heart, Kidney and Spleen channels, and acting to nourish yin, moisten dryness, nourish Blood and extinguish wind. It is used for irritability and insomnia, convulsions in heat disease, consumptive vomiting of blood, vomiting and diarrhea. Sweet and neutral, it suits yin-vacuity dryness-heat and Blood vacuity—not phlegm-damp, or Spleen vacuity with overeating.

How do you choose raw versus cooked yolk? Can E Jiao replace it?

Raw or mixed with a medicinal decoction leans to nourishing yin and extinguishing wind. Cooking leans to nourishing Blood. Donkey-hide glue is stronger for supplementing Blood; it cannot replace extinguishing wind by equal weight. Commercial yolk powder is not equal-weight pieces. Raw use requires fresh, hygienic eggs.
