Don't be silly.
lime is considered to be less harmful to human health than many of its modern counterparts:
■ lime plaster is hygroscopic (literally means ‘water seeking’) which draws the moisture from the internal to the external environment, this helps to regulate humidity creating a more comfortable living environment as well as helping to control condensation and mould growth which have been shown to have links to allergies and asthmas. The American College of Allergies suggest that 50% of all allergies are aggravated or
caused by our ‘polluted’ internal environment, thus lime creates a healthier living space.
■ lime plasters and paints are non-toxic, therefore they do not contribute to indoor air pollution unlike many modern paints.

Like I've already said "you don't know what you are talking about" best you move on.
