This little plant may seems harmless to all of us. It looks just like a coconut tree. It has a lot of benefits for us but also the bad influence. I received an email this morning about what bad can this little plant here do to human and also dogs. A chemicals in the plant cycasin is toxic and would cause permanent liver damage and neurological damage. Of all, the seeds is the most poisonous part and it may cause coma or worst, death.
