Thank you both so very much, it is funny, I just found this on an alternative site, I hope it is ok to post it here.
I just found this information, I am not good at this cutting and pasting but will try. It is from an acupuncturist and is talking about the liver. I thought it was interesting
Controls the Tendons & Sinews
The tendons are the main tissues linking the joints and muscles, and dominate the movement of the limbs. The liver nourishes the tendons of the whole body to maintain their normal physiological activities. Thus, when liver blood is deficient, it may deprive the tendons of nourishment and give rise to weakness of the tendons, numbness of the limbs, and dysfunction of the joints. When the tendons are invaded by the pathogenic heat of the liver caused by liver yang rising or by chronic liver qi stagnation, there may be convulsions of the four extremities, opisthotonos and clenching of the teeth.
Opens Into the Eyes
The free movement of the blood from the liver gives the eyes their brightness and shine. When liver blood is abundant the vision is clear and crisp. When it is deficient, the vision is blurred, dry and conditions such as myopia can develop. If the liver fire or yang is rising, heat can get into the eyes and cause them to be red, dry, irritated. If the fire is strong enough to become wind, it may cause the eyes to turn upwards or to move involuntarily.
Manifests in the Nails
When liver blood is ample, the tendons and nails are strong, and when liver blood is deficient, the nails become soft and brittle.
