The Gastrotonia constitution is configured in a way in which the stomach is the strongest out of the organs, meaning that the organs are united and influenced by the stomach. Out of the 5 solid and 5 hollow organs, this constitution retains the strongest stomach intestines and the weakest bladder. All diseases occur as the result of either of the two choices: 1) the strongest stomach intestines become stronger, or 2) the weakest bladder becomes weaker. The strengthening and weakening of the stomach intestines and bladder influence the other organs to function abnormally. The Gastrotonia constitution is practically the mix between the Pulmotonia and Pancreotonia constitutions, in which the acute diseases can be treated by either adhering to the Pulmotonia constitution treatment or the Pancreotonia constitution treatment.

Organ Configuration (from strongest to weakest):
Stomach >Large Intestine >Small Intestine >Gallbladder >Bladder
5 > 4 > 3 >2 >1 (EnergyMagnitude)

Body Form and Characteristics:
It is quite rare for an individual to be born with the Gastrotonia constitution (1 in 100,000-200,000 individuals). Although people of the Gastrotonia constitution do not appear to be in a hurry regularly, they tend to not know what to do or act frantically when an urgent situation arises. The Gastrotonia constitution is prone to side effects of Western medicine (this constitution may cause penicillin shock in some cases), so one must be always careful. A test of diluting penicillin to 1/100 and placing it in the eyes could be done to discover who are sensitive to penicillin (congestion occurs for individuals of the Gastrotonia, Pancreotonia, and Pulmotonia constitutions). People of this constitution are characterized by their bird chests which are often narrow and protrude forward. Additionally, people of this constitution are relatively free from minor illnesses and dislike visiting the hospital.

Due to the tendency of side effects from medicine intake, a person of this constitution must be on guard. Rather than greasy foods, one must adhere to fresh and cold foods. People of this constitution must stay away from exercises that require excessive sweating, cold baths, and alcohol.

Optimal Foods (normalize the strengthened stomach intestines):
Pork, milk (cold), dairy products, cheese, egg whites, majority of saltwater fish, shellfish, oyster, shrimp, crab, ocean fish (with scales), swell fish, pea, kidney bean, peanut, almond, cashew, rice (white), barley, buckwheat, mung bean, rye, canola oil, olive oil, grapeseed oil, green vegetables (lettuce, cabbage, etc.), cucumber, stems of radish, spinach, Aster scaber, water dropwort, zucchini, avocado, watermelon, melon, Campbell early, grapes, strawberry, banana, pineapple, kiwi, pomegranate, blueberry, persimmon, cranberry, Reishi mushroom, Cornus Officinalis, aloe, Vitamin E, Dextrose injection, Dextrose powder, cold drinking water, Alkaline beverage, and ice.

* Multigrain rice made from barley (most optimal), white rice, and red bean will not only serve to eliminate heat in the pancreas and stomach intestine, but also strengthen the weakened kidney.
* Barley (barley rice, barley tea, barley drinks, etc.) serves to eliminate heat trapped within the strong stomach intestine and pancreas.
* Pork strengthens the weak kidney.
* Beef is very harmful (Gold element is the second strongest for this constitution).
* Seafood: Oyster (raw) serves to strengthen the weak kidney.
* Optimal fruits: Persimmon, pear, grapes, pineapple, strawberry, banana, etc.
* Vitamin E: Marvelous supplement in strengthening the weak kidney.
* Drinking cold water in the morning and consuming chocolate is highly beneficial.

Harmful Foods (worsen the weakened kidney):
Chicken, duck, poultry, goat, lamb, pistachios, acorn, pine nut, brown rice, sweet rice, crushed rice, sesame oil, perilla oil, potato, sweet potato (yam), Dioscorea opposita, beet, ginger, Chinese bellflower, taro, codonopsis, pepper (hot & spicy), scallion, onion, cinnamon, mustard, curry, garlic, seaweed, apple, clementine, orange, grapefruit, lemon, lime, mango, ginseng, red ginseng, antlers of the deer, honey, jujube, Chinese matrimony vine, Root of Ranunculaceae, Phellinus linteus (Aoshima), yuzu, Japanese apricot, Schisandra Chinensis, arrowroot, Vitamins (A, B, & D), ginger tea, jujube tea, chrysanthemum tea, Ssang Hwa tea, ginseng tea, warm drinking water, Acidic beverage, soda, alcohol (whiskey, vodka, unfiltered Korean rice sake, sake, soju), and smoking.

* Consuming spicy foods is very lethal to the body.
* Consuming too much seaweed will hinder blood circulation, leading to cold hands and feet.
* Smoking and consuming alcohol are detrimental to the body.
* Multigrain rice made from sweet rice and brown rice will expedite the heat collection in the pancreas and stomach intestine, leading to diabetes, arthritis, and incurable skin diseases.
* Root vegetables: Potatoes and sweet potatoes (yams) will worsen the heat collection in the pancreas and stomach intestine.
*Sesame oil worsens the heat collection in the pancreas and stomach intestine.
*Meats: Chicken, ginseng chicken soup, goat, lamb, deer, and duck worsen the heat collection in the pancreas and stomach intestine.
● Vitamin B group: worsens the heat collection in the pancreas and stomach intestine.
● Penicillin is harmful to the body.
● Digestive enzymes are harmful to the body.

Foods that are harmful when consumed too much:
Beef, butter, egg yolk, freshwater fish, ocean fish (w/o scales), bean, soybean, fermented soybean (natto), African/Indian millet, corn, flour, Job’s tears, oat, soy oil, corn oil, root vegetables (radish, carrot, lotus rook, burdock, etc.), spinach, perilla leaf, Allium tuberosum, pumpkin, eggplant, mushrooms (matsutake, shiitake, oyster, etc.), sugar, seaweed, pear, papaya, peach, plum, cherry, apricot, Chinese matrimony vine, quince, Vitamin C, caffeinated drinks (coffee, tea, soda), green tea, Adlay tea, quince tea, cocoa (chocolate), and alcohol (beer & wine).

Accessories and Activities:
Optimal: wearing accessories of silver, breathing exercise (exhaling).
Harmful when done or worn too often: breathing exercise (exhaling), swimming, cold bath, sun tanning, hiking (in dense forest), and wearing accessories of gold or jade.

Omitted due to the distribution ratio being extremely low.

Optimal Marriage Partner:
An ideal partner for an individual of the Gastrotonia constitution is listed in order from the most optimal: Vesicotonia, Hepatonia, and Renotonia.

Optimal Colors:
Optimal colors for people of this constitution are blue and black colors, while red and yellow colors are harmful to their bodies.

Alcohol Use:
Due to the extensive heat trapped within the stomach intestine, one must stay away from alcohol (if alcohol consumption cannot be avoided, avoid strong liquors and stick to beers).

Although Atopic dermatitis is predominantly acquired by people of Pulmotonia constitution, a person of this constitution may acquire it as well (Pulmotonia and Gastrotonia constitutions retain strong Gold and Earth elements). Atopic dermatitis is common among children, in which they acquire the disease from eating too much meat (Gold is the second strongest element for this constitution). In this case, injecting Dextrose injection works to alleviate the symptoms of Atopic dermatitis.

Penicillin Shock with a frequency occurring less than once in tens of thousands of cases can certainly be experienced by an individual (one in several hundred thousand) of this constitution. People of this constitution experience gastrointestinal diseases, constipation, headache, and skin diseases. If an individual of this constitution consumes foods that emit heat (chicken), the stomach intestine appears shrunken in the X-ray. While a person of Pancreotonia may survive from consuming spicy foods, a person of Gastrotonia constitution will suffer miserably.
