Metal
The meridians associated with the metal lodge are those of the large intestine (Ic20) and the lungs (Po10), with their primary function of exchange and elimination. The basic emotion is sadness, with various nuances that can change based on the state of the energy flow of the aforementioned meridians.

Negative emotions: introversion, tendency towards depression, inflexibility, aridity of feelings, greed.
The Lung Meridian, with its 10 points, begins in the deltopectoral triangle below the coracoid process (clavicle) and ends at the outer nail tip of the thumb; this is considered to be homolateral.
The Large Intestine Meridian, with its 20 points, begins at the inner nail tip of the index finger and ends in the direction of the masseter muscle, on the face next to the nose.

Fire
The meridians associated with the Fire Lodge are the Heart, Heart Master, Triple Warmer, and Small Intestine. The associated emotion is joy; its positive aspects evoke sensitivity, extroversion, and the ability to love. Its negative aspects, however, tend toward hypersensitivity, victimhood, anxiety, fickleness, and lack of affection.
The first of the nine points of the Heart Channel begins in the center of the armpit and ends at the tip of the little finger. Keywords: interpretation, emotions (compassion, empathy, love), laughter, willpower, self-reflection.
The Small Intestine Meridian (It19) begins on the ulnar side of the little finger, ascending along the outer side of the arm, passing over the shoulder blade, and ends in front of the ear at its nineteenth point. Keywords: assimilation (including of ideas), absorption, discernment of emotions, strong determination.
The Triple Warmer Meridian (Tr 23) begins at the outer nail tip of the ring finger and ends just after the eyebrows in external vision.
The Pericardium Meridian, or Master of the Heart (Mc9), begins in the area of the seventh rib near the pectoralis major muscle at and toward the armpit and ends at the inner tip of the middle finger.

Earth
The meridians associated with the Earth Lodge are the Stomach (st45) and Spleen (m20).
These meridians, when balanced, generate positive emotions such as a sense of humanity, reflection, reassurance, decisiveness, and organizational ability intended to create stability. Their opposite aspect, however, generates emotions such as excessive shyness, anxiety, pedantry, self-pity, victimhood, and mistrust.
From an energetic perspective, the Stomach is the highest expression of yang energy. Its first point is located just below the center of the eye, and it runs along the entire front of the body until it reaches the second toe on the outer nail side. Keywords: digestive system, cyclical movements, breastfeeding, raising, nourishing, ingesting knowledge, appetite, greed, brooding, stubbornness, constriction, sympathy, worry.
The splenic canal begins at the outer tip of the big toe and ends on the side, halfway between the armpit and the edge of the eleventh rib. Keywords: reproductive system (hormone secretion), cycles, mental activity, sexual maturity, gives tone and shape to connective tissue.

Wood
The meridians associated with the Wood Lodge are: Liver (F14) and Gall Bladder (GB44). Their basic emotion is anger, and their primary function is storage and distribution. The characteristics generated by these meridians in balance are decision-making ability, creativity, patience, planning, and imagination. When unbalanced, however, they generate instability, nervousness, aggressiveness, a tendency to argue, and irritability.
The Liver is considered the army general; it is he who plans the best strategy to defend the body (having a gut). The meridian begins at the inner tip of the big toe and ends in the middle of the fifth rib in medial view. Keywords: storage, organization, elasticity and vigor of muscles, ligaments and tendons, mental elasticity.
The gallbladder’s function is to distribute energy throughout the body and separate the pure from the impure. This meridian is characterized by decision-making and responsibility. If the gallbladder’s action is blocked by energetic stagnation and therefore unable to make decisions, this can trigger anger, aggression, frustration, and dissatisfaction. The first point of this meridian arises at the outer edge of the eye, in the first deep soft spot after the bone, and ends at the outer edge of the fourth toe (pondulus) in its external vision. Keywords: discernment, decision, distribution.

Water
The meridians associated with the water lodge are the kidney meridian (R27) and the urinary bladder meridian (V67). Their primary bodily functions are fluid transport and purification.
The bladder meridian begins on the face at the inner edge of the eye and descends to the outer nail tip of the big toe. Keywords: fluid purification, drive, impetus, autonomic nervous system, pituitary gland (hypophysis), bone growth, joints, fatigue.
The kidney meridian begins on the sole of the foot under the second and third metacarpal bones and ascends along the body until it ends below the clavicle in the space of the first rib. According to traditional Chinese medicine, the kidneys are the treasurers of our Jing, the Jing of the anterior heaven and the jing of the posterior heaven, that is, the ancestral, genetic energies we inherit from our parents and those we can regenerate through food and air.
