Can you give me the amount of physiologic serum and also the method of following preparation? Urea 10g Coaltar 10g betametasonepropionate 40mg Cholesterol 3g physiologically

I would assume 10g which so I suspect all urea can be dissolved (possibly a little warming up). This solution hot emulsify in the petroleum jelly in which cholesterol was dissolved. Of Betamethasone Propionate make a 1 to 50 trituration and rub the correct weighed amount with the coal tar and rub this whole with the FULLY cooled CR è me.
