Proven palliative effect

• Massage therapy — massage has real benefits such as temporary pain relief and increased circulation, but like all other woo, some less ethical therapists will sell it (and a line of smelly herbal additives) as a cure for almost anything.
• Chiropractic — has been shown to relieve some back and joint pain and mitigate some chronic headaches. Has the disadvantage that it can damage soft tissues if done wrong.
• Medical marijuana — Some adhere to the smokable version of this despite issues with proper dosing; some of its medicinal properties are also found (and precisely dosed) in Marinol, its synthetic version.
• Osteopathy — In North America it is a variant of mainstream medicine, albeit one with slightly different approaches to medicinal problems. Outside of the US there appears to be a great deal more quackery involved.
• Various meditation, music, color, and aromatherapy treatments have limited but highly successful effects for dealing with chronic pain, chronic stress, and other minor psychological side effects like sleeplessness and temper. It should be noted, this last list is specific to dealing with these issues, and not actually changing the amount of pain or stress.
• Certain herbal remedies have beneficial effects so fall into this category.

Potentially provable

• Herbal supplements — some are fairly effective for some conditions; others close to useless. Herbal medicine varies a great deal in effectiveness and quality.
• Oil pulling — does have some effect against tooth decay. Not much else, though.
• Salt therapy — involves breathing in salt cave air.

Useless

Benign

• Aromatherapy — smelling nice has some social advantages and won't kill you. To cure anything other than the above, however, it's nonsensical.
• Reflexology^[4] — as a massage therapy it can reduce stress, but there is nothing it can cure.
• "Himalayan" salt lamps — do nothing except slightly light up the room.
• Bach flower remedies — since some of the issues these treat are psychosomatic, and some of the users are neurotics and hypochondriacs, flower remedies are perhaps the best thing for them.
• Homeopathy — using dilute solutions with no remaining active ingredient to treat conditions.
• Cupping — often used in conjunction with bloodletting.
• Magnetic field therapy
• Psychic surgery
• Reiki
