Treats severe itching extending to the bone, and itching within the ulcer cavity.
Take one *jin* (approx. 500g) of sesame oil and one hundred segments of green locustum branches (*Cercis chinensis*). Add them sequentially into the oil and boil until the branches are scorched and brittle, then remove the branches. Continue boiling until a drop of oil forms a bead when dropped into water (*dianshui chengzhu*). Add one *liang* and five *qian* (approx. 56.25g) each of beeswax and starch. Remove from fire; when the mixture is warm, add three *qian* (approx. 11.25g) each of processed *Boswelliae Cartharsii Resina* (Ru Xiang), *Myrrhae Resina* (Mo Yao), *Camelliae Semen* (Er Cha), and *Daboia sinensis* (Baihua She), one *liang* (approx. 37.5g) of *Borneolum Syntheticum* (Cha Nao), and one *qian* (approx. 3.75g) of *Moschus* (She Xiang). Stir uniformly with the oil to form an ointment. Soak in water overnight, then spread and apply.

Promotes tissue regeneration and wound contraction.
Take four *liang* (approx. 150g) of sesame oil, one *liang* and five *qian* (approx. 56.25g) of candle wax, and one *liang* and five *qian* (approx. 56.25g) of beeswax. Boil until a drop forms a bead in water. Remove from fire, add three *liang* (approx. 112.5g) of calcined lead powder. Then add five *qian* (approx. 18.75g) each of *Calomelas* (Qing Fen), *Boswelliae Cartharsii Resina* (Ru Xiang), *Myrrhae Resina* (Mo Yao), *Ferulae Resina* (A Wei), white wax, *Realgar* (Xiong Huang), *Ossum Draconis* (Long Gu), and *Concha Margaritifera* (Zhen Zhu), plus six *qian* (approx. 22.5g) of *Camelliae Semen* (Er Cha). Stir uniformly away from heat. Finally, add five *qian* (approx. 18.75g) of *Moschus* (She Xiang). The ointment is ready for use. This method is most effective for promoting tissue regeneration and wound contraction.

Highly effective for treating toxic abscesses penetrating through the head.
*Cuprum Carbonicum Viride* (Tong Qing), *Pini Rosin* (Song Xiang), *Boswelliae Cartharsii Resina* (Ru Xiang), *Myrrhae Resina* (Mo Yao), *Amygdalus Persicae Semen* (Xing Ren), raw *Momordicae Semen* powder (Sheng Mubie Fen), *Ricini Fructus* (Bima Ren) (equal parts); *Crotonis Fructus* (Badou) (do not remove oil, roast before use).
Grind all ingredients together into an ointment. For every *liang* (approx. 37.5g) of ointment, add one *fen* (approx. 0.375g) of white arsenic (*Bai Pi*), and stir uniformly. When applying, take a grain-sized amount (size of a mung bean), place it on the apex of the lesion, cover with the ointment. Once ulcerated, remove the dressing, wash clean, and apply fresh ointment. Contraindicated during pregnancy and postpartum.

Treats chronic non-healing leg ulcers.
Take one *jin* (approx. 500g) of black lead and melt it with three *qian* (approx. 11.25g) of white arsenic (*Bai Pi*). The next day, scrape off the surface layer of the lead; this is called "Golden-Topped Arsenic" (*Jinding Pi*). Melt the lead again and pour it out thinly like paper sheets. Cut into square patches according to the size of the ulcer hole. Prick twenty to thirty holes with a needle. Apply the smooth side directly onto the hole. Daily, wash the hole with a decoction of *Viola Yedoensis* herb (*Zihua Diding*) and wash the patch twice. Within three days, the toxic fluid will drain completely, and the color will turn red and vibrant. Apply *Fulong San* (prepared by wet-pulverization) over the area, and continue using the aforementioned patch externally. Avoid prolonged standing or walking, sexual intercourse, and consuming toxic foods. For women, application must begin only after menstruation has ended.
Master Ma said: All the above prescriptions are safe and effective.
The treatment methods in this book are extraordinarily miraculous. Some formulas utilize live animals such as ducks, toads, river snails, crucian carp, spiders, and centipedes. These are used only out of necessity. If the disease severity is not significant, these live creatures need not be used, thereby avoiding the karmic burden of killing living beings.
