Rudraksha come in different mukhis or furrows on the surface. Shastras speak of 1 to 38 mukhis but normally 1 to 14 mukhis are used for astrological benefits. Each bead has a different effect on you, depending on the number of mukhis it has. Each Rudraksha is very individualistic and has to be carefully matched with one's horoscope for it to be beneficial.
Mantra has a very important place for Rudraksha. Vedas have given special weightage to Rudraksha, as it is believed that Rudraksha has originated from the tears of lord Shiva. Rudraksha have tremendous energy and power. Rudraksha is best known for its biomedical properties and in controlling stress, hypertension and blood pressure. Rudraksha is available mainly in India, Nepal and Malaysia.

The chain of 108 beads or 52 beads if worn and worshipped provides all types of benefits. Therefore, it is important that Rudraksha should always be respected and kept pure. One should not touch it with dirty hands. It is a blessing to mankind. It is believed that one who wears Rudraksha on his body, cannot be affected by sins. Even if, one wears Rudraksha on his body, without doing worship and saying the sacred mantra, does no get near any sinful deed or thought.

The Rudraksha are worn for their specific benefits. These are much more powerful and can help achieve wonders, if energized and empowered the right way. Rudraksha of different mukhis pleases the corresponding planets. It may be sufficient to go in for only for those mukhis whose ruling planets, cause malefic effects.
