That's good information. I'm a professional herbal practitioner and your information follows the Chinese herbology principles. I can often determine the degree of liver/gallbladder congestion in someone by asking about "anger/impatience/frustration" that wells up inside a person with no apparent provocation. I ask them to measure on a scale of 1 to 10 (10 being the worst). Then, I blend a tonic that will relax and cleanse the congestion that causes these emotions. Within 2-3 days, they'll release these emotions and they go away. (The symptoms, not the patient. ha,ha)
Another symptom is also neck/shoulder tension arising from the congested energies rising from the liver/gallbladder meridian. These too leave within 2-3 days with a more relaxed feeling in the muscles even after getting off the tonics.
Another negative emotion (chronic) of "worry" will arise when there's a YIN deficiency which means when people have excessively dry mucous membranes.
Other systems can be associated with other negative emotions.
It's all very interesting and part of the natural sciences.
Thanks for sharing those links.
