Glycyrrhiza glabra

  • Licorice  (Glycyrrhiza glabra)
  • In TCM: gāncǎo (甘草) is used as a panacea
  • Beneficial effects: Licorice "acts as a demulcent, a soothing, coating agent, and as an expectorant."
  • Harmful effects: In large quantities, may have detrimental effects on heart disease, kidney disease, pregnant women, male sexual function, and may cause brain damage even in healthy people. In lower quantities, side effects may include tiredness, absence of a menstrual period in women, headache, water and sodium retention, decreased sexual interest and function in men, miscarriages or early deliveries, and raised blood pressure, and may also worsen heart and kidney disease.
    According to MedlinePlus Supplements, "Consuming  grams or more of licorice daily for several weeks can cause severe side effects including high blood pressure, low potassium in the blood, weakness, paralysis, and occasionally brain damage in otherwise healthy people. In people who eat a lot of salt or have heart disease, kidney disease, or high blood pressure, as little as  grams per day can cause these problems." Licorice "might act like estrogen in the body. If you have any condition such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids that might be made worse by exposure to estrogen, don’t use licorice." Licorice can interact with grapefruit juice, possibly increasing its ability to deplete human potassium levels, and licorice's side effects of sodium and water retention and increase in blood pressure can worsen if taken with salt.
    Licorice can interact with heart medicines, steroids, diuretics, or insulin.

 

Gaultheria procumbens

  • Wintergreen  (Gaultheria procumbens)
  • Used for: pain relief (contains methyl salicylate, which is similar to aspirin or acetylsalicylic acid), urinary ailments, colic and farting
  • Insufficient research to evaluate efficacy. Used for asthma, rheumatism, and headache.
  • Harmful effects: Wintergreen is safe, but internally taken wintegreen oil is toxic and can cause ringing in the ears, nausea, vomiting, diarrhea, headache, stomach pain, confusion, and death. (Wintergreen oil contains methyl salicylate, and  mL of the oil is equivalent to about . aspirin tablets.) Topical use can cause skin irritation.

 

 

Ginkgo biloba

  • Ginkgo  (Ginkgo biloba)
  • In TCM: yínxìng(銀杏)
  • The nut-like seeds of gingko have been consumed as both a food and as a medicine by the Chinese and other East Asian cultures for centuries. That the seeds are mildly toxic due to trace amounts of the compound '-O-methylpyridoxine (MPN) has never discouraged Asian people from eating them, though, it is advised to limit the seeds' consumption by children. The fleshy coating of the seeds can potentially cause irritating skin rashes if touched by sensitive people.
  • Ginkgo leaves contain flavonoid glycosides (myricetin and quercetin) and terpenoids (ginkgolides, bilobalides).
  • In Western medicine/herbalism, ginkgo is sold as a "memory aid" and a treatment for Alzheimer's disease. Studies show mixed results on efficacy, with a possibility of it being better than placebo.
  • A cancer study of ginkgo extract found that it "caused cancers of the thyroid gland in male and female rats and male mice and cancers of the liver in male and female mice."
