Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Acne: Recommendations are easy; data, scarce

    Herbalists recommend more than a dozen herbal remedies for acne and scarring, according to a recent article.

    Unfortunately, only 1 of these herbals is supported by the results of a study in patients.

    First, the details.

    • The study was of 5% topical tea tree oil gel.
    • 60 patients with mild to moderate acne vulgaris were randomly assigned to 45 days of treatment.
      • 5% topically applied tea tree oil gel
      • Placebo
    • Response to treatment was evaluated by counting the acne lesions and the acne severity index.
    • Neither the patients nor researchers knew the treatment given — double blind.

    And, the results.

    • Tea tree oil gel was significantly superior to placebo in reducing the total acne lesion count — 3.55 times more effective.
    • There was significantly greater improvement with tea tree oil gel vs. placebo in acne severity — 5.75 times.
    • Side effects to both treatments were relatively similar and tolerable.

    Here’s a list of commonly recommended herbals that lack support based on the findings of PubMed literature searches of patients with acne.

    • Black currant seed oil
      • 500 mg capsules 3 times daily for 3 months or until acne is diminished.
    • Evening primrose oil
      • 500 mg capsules 3 times daily for 3 months or until acne is diminished.
    • Teas from a combination of echinacea, tea tree oil, goldenseal, nettles, or calendula.
    • Teas from lavender or chamomile
      • To reduce acne-causing stress.
    • Chinese herbs
      • Cnidium seed
      • Honeysuckle flower
    • Teas from cumin, coriander, and fennel
      • Steeped for 10 minutes in hot water and consumed 3 times a day after meals.

    The bottom line?
    It’s surprising how detailed the treatment recommendations are considering the lack of evidence that these herbals make a positive contribution to the management of acne.
