Dr. Roovers has succeeded in treating my allergies to the full extent. For over 20 years, I had…read morebeen suffering from an increasing asthmatic condition, related to hay-fever and general allergies. The condition forced me to use an inhaler (Duovent) in ever increasing amounts (up to 7 inhalations per day, which is way beyond the suggested use of this medication). My regular physician tried to switch me to cortisone inhalers, which I refused. After getting a specialists opinion I was given the same advice (cortisone). Again, I refused. Only after meeting with Dr. Roovers, who gave me homeopathic solutions to recalibrate my immune system, I am down to 1 inhalation per month, and only when I am confronted with an extreme trigger (like inhaling heavy fumes from a passing diesel truck, when I'm riding my bike at full speed). My resistance to allergy triggers is up to 95%, where it used to be closer to 30 or 40%. So, I can only give a raving review. Thanks.
