    There are many names of snake root such as richweed, white sanicle, tall boneset or Ageratina altissima.
    It is a perennial plant which means lives for more than 2 years.An older binomial name for this species is Eupatorium rugosum. White snakeroot contains the toxin tremetol. Due to tremetol vomiting, intestinal pain is caused. Technical it is called milk sickness. When cattle consumes it, through meat and milk it is passed to humna beings causing tremetol poisoning in humans.

  2. Wisteria belongs to legume family Fabaceae. Peas and beans are examples of legume. These are native to china, korea and japan. Very harmful for dog and cats.

    Subsequent toxic effects included headache, gastroenteritis, hematemesis, dizziness, confusion, diaphoresis,

    This attracts a lot of people but awareness or prevention is better than cure.
