Nourishing, destructive and neutral substances

Curd, ghee, milk, buttermilk, barley, shāli rice, lentil, jaggery and the like are said not to be a cause of sin and to nourish one's welfare, so they are called nourishing.

Poison, honey, wine, meat and the like are said to cause great sin and to ruin life after life, so they are called destructive.

Grass, many trees, shrubs and creepers are said to be neither nourishing nor destructive for people, but are regarded in the world as not to be eaten.

Everything in the world is said to be of three kinds: having a nourishing quality, having a destructive quality, or having neither.
