Polygonum multiflorum dried roots

  • He shou wu (何首乌) (Polygonum multiflorum )
  • Claimed to be a cure for baldness and grey hair, as well as being promoted as a immune system booster (though he shou wu contains emodin, a possibly immunosuppresant substance).<wiki/List_of_medicinal_plants#cite_note-hsu-225"> There's not enough evidence to evaluate claims.<wiki/List_of_medicinal_plants#cite_note-hsu-225">

 

Petroselinum crispum

  • Parsley  (Petroselinum crispum)
  • Used for: edema, jaundice, asthma, coughs, menstrual problems, conjunctivitis and blepharitis.<wiki/List_of_medicinal_plants#cite_note-theherbbook-7"> It is sometimes used for home abortions, but its effectiveness for this has not been scientifically studied.
  • The claims: Parsley is touted as a general anti-toxin,<wiki/List_of_medicinal_plants#cite_note-171"> control blood pressure, cure diabetes,<wiki/List_of_medicinal_plants#cite_note-172"> urinary tract infections, prevents cancer, stimulates contractions of the uterus, cures rheumatism, treats kidney and bladder stones,<wiki/List_of_medicinal_plants#cite_note-173"> and can even remove tooth aches.
  • The truth: Surprisingly, it is dangerous for women, as it can cause the uterus to contract prematurely and should not be inserted into or rubbed near the uterus. It is mildly anti-microbialial — on those days when you can't run to your medicine cabinet and grab a tube of far more effective antibiotic.
  • Harmful effects: It is harmless when taken in the small amounts found in food, but the large amounts used in herbal medicine may cause anemia and liver or kidney problems, and make water retention, high blood pressure, and kidney disease worse.<wiki/List_of_medicinal_plants#cite_note-parsley-174"> Topically applied parsley oil can make skin become more sensitive to sunlight and cause a rash.<wiki/List_of_medicinal_plants#cite_note-parsley-174">
