scabies
"Works good, but the bug has to bite you in order for it to be effective. Administered by body weight formula. Saturation to full strength within 4 hours after ingestion. Remains at full strength for appx. 18 hours. Dissipation afterwards  at appx. 2.5mg per day. Estimated half life is 12 days per dose. All conditions depend on body weight. Kills bugs wherever they feed, including those in the skin, which may cause ulcers from the decomposing dead parasite. Effectiveness on pre-existing eggs is questionable. Work closely with a doctor on the dosage and saturation levels or overlap doses. Keep records on reactions/results."
