Healing is another special ability granted to Whitelighters, and is used when their charges have been injured. As long as there is the faintest breath of life left in a person, they can be healed from any injury, whether the injury is magical in origin or not, though they cannot heal self-inflicted damage. A Whitelighter's healing abilitiy is triggered by the emotion of love.

Whitelighters are normally not allowed to have relationships with witches as it is deemed to be too complicated and dangerous by the Elders. There are several half-Whitelighters due to this rule being broken or lifted in special circumstances by the Elders. The four known half-Whitelighters (three in the Halliwell family) are Paige Matthews, Wyatt Halliwell, Chris Halliwell and Sir Simon Marks. All four display most of the abilities of Whitelighters. Wyatt is able to heal, Chris cannot, and Paige apparently can channel Leo's power; during the 8th season, she gains the healing ability for herself. Sir Simon, on the other hand, is a mystery; little is known about him. What is known is that he has the ability to orb himself and he can orb objects with his mind. Whether or not he possesses the ability to heal is unknown.

Because they are pacifists, Whitelighters traditionally avoid fighting, except when desperately needed to protect their charges, but are absolutely not allowed to kill. Leo tries to force Chris into a hearing with the Elders after he suspects (correctly) that Chris killed two warriors in Valhalla, and Leo himself brings balance back into the world of magic by doing a "Great Evil" in killing Gideon.

Among the other powers of Whitelighters are levitation, invisibility, and "cloaking" their charges (making others unable to sense them). Whitelighters can also empathically feel what their charges feel (which, if not controlled, can actually hurt them), knowing if they are hurt or have been killed. White lighters can also summon/create orbs of light. They also have the ability to speak the language of their charges, whatever it may be, and their own sort of glossolalia. Leo is also seen "healing" household appliances, light bulbs, and pipes, and making Phoebe's tea hot again and refilling her water. In one episode during the first season where we first realize that Leo has powers, but not that he is a Whitelighter, we see him "heal" the Charmed Ones' Book of Shadows, which had been erased after the Charmed Ones used the spell to relinquish their powers to a Warlock, thus rewriting the entire book and giving back the sisters' powers. Whitelighters also have their own language, which sounds to human ears like a series of clicks and clacks but to them sounds like words. Whitelighters have also displayed the ability to "orb into anyone" which allows them to take the physical form of others. Many tend to confuse this with Glamouring. Glamouring casts an illusion around the being, making it look like another, while orbing inot another actually transforms the being into another. Paige has this ability. While Phoebe and Piper Halliwell have been shown to glamour both themselves and others(in the 7th season finally and at the beginning of the 8th season)), leading us to believe that this is a Whitelighter-exclusive power. Whitelighters also appear to have the ability to mimic certain demonic powers such as energy-balls as Leo Wyatt does when he glamours into the demon Belthazor to train the sisters and as Natalie does while training the sisters to kill a powerful warlock named Eames. Natalie is a fellow Whitelighter and longtime friend of Leo Wyatt during both their Whitelighter years and human years when they fought together in World War II. While Whitelighters have the ability to mimic demonic powers, they are not allowed to use them unless they are training their witch charges. It is unknown, however, if the demonic powers that they mimic have the same effect that they would if an actual demon were to use it. It is believed by many that because of their pacifism they are not able to mimic high-voltage energy-balls, for fear that it might hurt their charges while training them. Elders, whose powers seem to be stronger versions of Whitelighter powers, can throw lightning bolts. Lightning bolts are only used in extreme circumstances such as Leo Wyatt uses when he commits a great evil to restore the balance of good and evil in the two mirroring worlds by killing the Elder Gideon when he tries to kill Leo's son Wyatt. The Elders use them when they try to kill Leo after they view him as a threat after he discloses to them that he is an Avatar.

Whitelighters can pass some, and perhaps in some cases, all, of these abilities on to their offspring. Chris and Paige are able to orb and sense others, channel the ability to heal through another Whitelighter, heal on their own, and speak any language other than their own. Chris cannot levitate, though Paige can. They are, however, still very vulnerable to Darklighter arrows. Paige heals Henry without channeling a Whitelighter's power during an emotional scene that unlocks her power (this could be the natural evolution of her witch powers that the Charmed Ones all have). Until that time, it was thought that half-Whitelighters can not heal, but now it is possible that Chris will eventually gain the healing ability.

Whitelighters have shown a wide range of powers, sometimes appearing when they are convenient and then never appearing again. When Leo explains his powers to Phoebe, he states that they can do whatever their charges need them to do. It is possible, for this reason, that they can only perform certain magics when it benefits their charges, but are otherwise powerless (with the exeception of orbing, healing, and hovering).
