In Ayurved are considered to be tamsik (a negative term against health) as they cause adverse sensations in the total body system.This could be one aspect but in totality chillies contain medicinal properties which otherwise are great boosters to an overall functional system of the body. Lata Mangeshkar, the great legend in the music world, takes plenty of chillies with the belief that it gives better health to the voice of the user. None of the eatables are cent per cent beneficial or harmful. Much depends as to how a person monitors her/ his doze. Combination is the key factor. If a person takes chillies without a proper dietary support it may cause hell of a problem but the very intake is quite helpful if it is taken by fixing its quantity proportionately on the basis of other food items taken along with it.
