👉 Ereiconastes is a concept in ancient Greek medicine that describes the condition where the body's energy, particularly its vital energies (such as blood and qi), becomes depleted or exhausted, leading to symptoms such as weakness, fatigue, and illness. This state can be characterized by an imbalance of the heart and lungs, along with other organs like the liver and kidneys, which contribute to a general feeling of exhaustion and sluggishness.
