No, boric acid can still be very dangerous to humans, animals, and children. It may requires a lot of it for a lethal dose, but there are also several side effects of exposure to boric acid.

Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
Hydrogen bonds hold together the atoms in a water molecule. A single water molecule is made up of two hydrogen atoms and one oxygen atom. When a water molecule is formed between hydrogen and oxygen atoms, the oxygen atom ends up with a partial negative charge and the two hydrogen atoms end up with partial positive charges. The hydrogen bonds formed are responsible for the stabilized structure of water.
