Indoor plants almost immediately come under a scanner with three major unfavorable elements that they tend to bring with them into our homes which can have an ill effect not only on humans but also on our pets and animals. The three harmful components are –

  • The growth of mold – Damp soil of indoor plants can cause the growth of mold which in turn causes allergies and aggravates many grievances, especially for that of an asthma patient.
  • Indoor pollen – While choosing your indoor plant go for the ones that do not emit too much pollen as this can be a major cause of allergies.
  • Dust – Often overlooked but dust can be a prime cause of allergies. The dust that accumulates on the leaves and flowers of indoor plants can scatter harmful bits into the air that we breathe in fact spoiling the air-purifying qualities that indoor plants are known to have. This can be avoided by wiping the dust off as often as possible and keeping your plant clean.
