【Clinical Applications of Di Yu】
1. Treatment of intestinal typhoid in children
Use 1 liang of Di Yu and 5 qian of Bai Hua She She Cao for children aged 4 to 14. Cook them in 3 bowls of water until the volume is reduced to 60 ml and take it orally. For children under 4 years old, reduce the dosage by half. Take it 2 to 3 times a day and switch to once a day after the body temperature drops, until the stool culture is negative.
Experimental results have shown that 1:5 or 1:10 Di Yu decoctions have antibacterial effects. No side effects were observed during the treatment.
2. Treatment of burns
Dry and grind Di Yu into fine powder, and sift it; boil sesame oil (or vegetable oil), then quickly add Di Yu powder and stir to form a paste. Put it in a sterilized container for later use.
When using it, apply the medicine paste directly to the wound. It can quickly form a thick scab, which can prevent and control infection, relieve pain, and promote rapid wound healing.
3. Treatment of skin diseases
Roast Di Yu until it turns yellow, grind it into fine powder, and mix it with vaseline to make a 30% ointment for external application on the affected area. It is suitable for acute, subacute, seborrheic eczema, infantile eczema, and acute exacerbation of chronic eczema.
When there is more exudate, after the exudate decreases, mix 20 liang of Di Shu, 20 liang of roasted gypsum, and 1 qian of alum into fine powder and mix well, then make it into a 40 to 50% ointment for external application, once or twice a day.
In the case of subacute or chronic eczema with infiltrated skin lesions or mild hypertrophy, mix 1.5 liang of Di Yu powder, 3 liang of Mituo Seng powder, and vaseline into a 50 to 60% ointment for external application, once or twice a day.
4. Treatment of tuberculous abscess and chronic osteomyelitis
Prepare an injection solution with Di Yu, with a concentration of 2 grams of raw herbs per 2 ml. Inject 4 ml intramuscularly once a day, or take a 5% concentrated decoction of Di Yu orally, once a day. Adjust the dosage for children.
