I used demal 200 on a recent trip to Sri Lanka. I didn’t want to use standard anti malarials as I’d heard so many horror stories of side effects & still having the risk of contracting malaria. I was glad I discovered Demal as despite being bitten numerous times, I’m infection free. Everyone else on my tour was taking prescribed medication with the usual side effects & I was pleased to tell them all about Demal. I’ve also told some other friends of mine about it who are planning a trip to SE Asia.
