if simillimum is really correct - 30C should give at least *some* very clear sign. no doubt about that. and it should stick longer - may be months - for a single dose. follow dr prafull vijayakar methods for posology/case follow up and use morrison's desktop guide + radar keynotes version 4 / tinus smits practical mat. med to confirm the remedy. I find that a 200C (SBL, india) remedy - if really the correct simillimum for a chronic case lasts at least 7 months (7-8 months). my experience: wrong remedy/partial similia 200C does not show hering's laws in action and the effect clears up in about 2 months. rajan sankaran theories (with due respect) do not help at all. dr manish agarwala
