Cat’s Eye or Lehsunia is a powerful gemstone, but not for all since it has to be cleansed before being worn. Since they are astrological, they should not be worn by people with specific astrology problems or deficiencies. If one is easily worried, overly stressed, or of a weak nervous system, the impact of this particular crystal can be enhanced. It will be also advisable that individuals with a sensitive digestion or who are experiencing some digestion related complications should be careful as regular use of Cat’s Eye may worsen the situation. It is also advisable that people with a history of heart ailments should seek prior medical advice before wearing Lehsunia. Possible side effects of wearing Cat’s Eye include charges in the wearer’s emotional state, insomnia or vertigo. It is wise to seek the services of a qualified astrologer or a gemologist to determine if it is suitable for the intended purpose.
