Two people will come to the health clinic. One of them is an older, 72-year-old man. He is tall, thin, has naturally fair skin, often has cold hands and feet, has thoughts at night and suffers from insomnia. His skin is rather dry, his hair has always been thin and fine and his digestion is very sensitive. Today he came to the doctor with an itchy and red rash. The second person is a woman shortly in her forties. Her figure could be described as medium or athletic, she has rather oily skin, a great appetite, she is alert and often hungry. She also came to the doctor today with a red and itchy rash.
