Syndrome of deficiency of blood

The syndrome of deficiency of blood occurs when there is insufficient blood to nourish zang - fu organs and meridians.

Clinical manifestations : Pallor or sallow complexion, pale lips, dizziness, blurring of vision, palpitations, insomnia, numbness of the hands and feet, a pale tongue and a thready pulse.

Etiology and pathology : This syndrome is often due to weakness of the spleen and stomach, hence qi and blood have an insufficient source, or due to excessive blood loss, or drastic emotional changes which consume yin blood. Deficiency of blood deprives the head, eyes and face of nourishment, causing dizziness, blurring of vision, pallor or sallow complexion and pale lips. Blood, failing to nourish the heart, may lead to disturbance of the mind, palpitations and insomnia appear. Numbness of the hands and feet originates from the lack of nourishment of meridians and collaterals. The pale tongue is a result of the deficiency of blood depriving the tongue of nourishment, whilst the thready pulse is a consequence of insufficient blood in the vessels.
