Organ temperaments

Stomach Evidence: A

In Persian medicine the stomach is the body's "cooking pot".

Hot dominance
Heartburn, acid reflux, false appetite (hungry even when full), great thirst after meals.
Cold dominance
Slow digestion, long heaviness after meals, aversion to cold food, odourless or cold-sour belching.
Wet dominance
Excess saliva, slow to feel full, a watery feeling of fullness.
Dry dominance
Dry mouth, full quickly but hungry again soon, accompanying constipation.
Link with sleep, digestion and excretion
A hot stomach usually comes with a strong appetite and regular bowels; a cold stomach with slow digestion and sometimes cold constipation.
Liver Evidence: A

The liver is regarded as the factory of blood and the humours.

Hot dominance
Local warmth under the right ribs, high tolerance of fatty food, dark urine, warm complexion.
Cold dominance
Slow fat metabolism, fats digest slowly, relative pallor.
Wet dominance
Accumulation of fat and phlegm, oilier skin.
Dry dominance
Dry abdominal skin, less abdominal hair.
Link with sleep, digestion and excretion
A cold, wet liver is associated with fatty liver and slow fat digestion; a hot liver with dark urine and high fat tolerance.
Kidney Evidence: B

In Persian medicine the kidney filters water and waste humours.

Hot dominance
Dark, strong-smelling urine, great thirst, local warmth in the lower back.
Cold dominance
Pale, copious urine, local coldness in the lower back.
Wet dominance
Frequent urination, a damp feeling in the lower back.
Dry dominance
Repeated thirst, dryness of the urinary tract, concentrated urine.
Link with urine
This organ is most directly linked to the quality and volume of urine; its colour, smell and frequency are the main clues to the kidney temperament.
Spleen Evidence: B

The spleen is regarded as the seat of natural black bile and is slightly cold by nature.

Hot dominance
Rarely seen, because the spleen is cold by nature; when present, it comes with hot bloating and inflammation.
Cold dominance
Bloating in the upper left abdomen, sluggish digestion.
Wet dominance
Rarely dominant.
Dry dominance
Dark skin, a mood tending toward melancholy, pessimism or obsessive thinking.
Link with the mind
In Persian medicine the spleen is directly linked to mental states (worry, obsession, sadness).
Bowel Evidence: B

The bowel is responsible for the final absorption of food and the excretion of waste.

Hot dominance
Hot colic, bilious (burning) diarrhoea.
Cold dominance
Cold constipation, cold and painless bloating.
Wet dominance
Much rumbling, soft stools.
Dry dominance
Dry, hard constipation; little but uncomfortable bloating.
Link with stool
The main clue to the bowel temperament is precisely the texture and regularity of the stool.
Brain Evidence: A

In Persian medicine the brain is regarded as cold and wet by nature.

Hot dominance
Insomnia, mental restlessness, passing forgetfulness, a turbulent mind.
Cold dominance
Daytime drowsiness, a heavy head, slow thinking.
Wet dominance
Heavy, long sleep, weak short-term memory, many dreams.

Link with sleep
The quality and amount of sleep is the clearest mirror of the brain temperament.

In Persian medicine the heart is regarded as hot and dry by nature and the source of the body's innate heat.

Hot dominance
Palpitations, warmth in the chest, high tolerance of physical activity.
Cold dominance
Weak pulse, listlessness, intolerance of physical activity.
Wet dominance
Rarely seen, because the heart is dry by nature.
Dry dominance
Dry palpitations (a fluttering feeling without excess moisture), anxiety.
Important warning
Any chest pain or shortness of breath on light activity must be followed up medically at once, regardless of temperament and apart from this assessment.
Uterus Evidence: C

The uterus is regarded as connected with major organs such as the brain, heart, liver, kidneys and stomach.

Hot dominance
Bright, heavy bleeding, pelvic warmth, period pain that improves with cold.
Cold dominance
Period pain that improves with warmth (a hot-water bottle), pale discharge.

Note
This section has no independent validated questionnaire yet; read its result with more caution than the other organs.

Balancing guide

Important warning before use: what follows is general Persian-medicine advice for "balancing" a dominant quality, not a personal prescription. Medicinal herbs, especially for people who are pregnant, breastfeeding, have an underlying illness or take conventional drugs, must be used under the supervision of a Persian-medicine specialist or a physician, because some herbs interact with drugs.
For hot and bilious temperaments (dominant heat, with or without dryness)
Diet
Cooling foods such as yoghurt, cucumber, lettuce, spinach and lentils; less hot, fried and spiced food.
Herbs & fruit
Flixweed seed, basil seed, borage flower (for cooling), diluted lemon juice, sour pomegranate, melon, watermelon, black plum.
Lifestyle
More rest in the hot hours of the day, no strenuous activity in the sun, lukewarm rather than hot showers, enough regular sleep.
Other
Avoid anger and constant stress (they add heat); a cool, dimly lit place to relax.
For cold and phlegmatic temperaments (dominant cold, with or without wetness)
Diet
Warming foods such as cinnamon, ginger, honey, walnuts and dates; less cold and raw food such as salad and ice cream.
Herbs & fruit
Ginger, cinnamon, fennel, quince, apple, dried fig, jujube (for warmth and clearing phlegm).
Lifestyle
Regular, vigorous exercise to warm the body, warm baths, avoiding cold and damp weather, warm clothing.
Other
Massage with warm oils (such as sesame oil); avoid long daytime sleep.
For wet and phlegmatic temperaments (dominant wetness, with or without cold)
Diet
Drying foods such as honey, garlic and warm spices; less full-fat dairy and fatty, sweet food.
Herbs & fruit
Pennyroyal, thyme, cinnamon, cumin, quince (to dry excess moisture).
Lifestyle
Regular physical activity to prevent stagnation and build-up of moisture, no long daytime sleep, dry and sunny air.
Other
Cut down on excessive, unnecessary fluids; cupping (only if a specialist advises it) to reduce excess moisture.
For dry and melancholic temperaments (dominant dryness, with or without cold)
Diet
Moistening foods such as soup, pottage, squash, spinach, fresh milk (if tolerated) and juicy fruit such as peaches and pears.
Herbs & fruit
Sweet almond, flaxseed, purslane, liquorice, juicy plums.
Lifestyle
Regular moisturising oils on the skin, lukewarm baths, enough water through the day, regular sleep and rest.
Other
For the melancholic, special attention to peace of mind and less rumination is advised; calming activities such as walks in nature or gentle music are considered helpful.
For the sanguine temperament (heat and wetness together)
Diet
A balance of cooling and slightly drying foods; less very fatty and very sweet food.
Herbs & fruit
Quince, pomegranate, tamarind (mild and balancing).
Lifestyle
Regular exercise, but not in great heat; as this temperament is usually balanced and healthy, the emphasis is on keeping that balance with a regular lifestyle.
Other
Avoid overeating and excess, as these people have a good appetite.
