Alyssa Milano has at least 7 known tattoos:
Alyssa Milano has a tattoo on her right wrist of a green and purple snake in a circle, biting its own tail. This symbol is called an “Ouroboros” and it was used in ancient Greece and Egypt. It represents the cyclical nature of life and the universe.
Alyssa Milano’s back tattoo is the Tibetan syllable “Hum.” Along with the “Om” tattoo on her wrist, this symbol is part of the Buddhist meditation Om Mani Bêmê Hum（ༀམཎིཔདྨེཧཱུྃ། in Tibetan) which translates to “jewel in the lotus.” Both the Hum and Om symbols are merely sounds without linguistic meaning.
