This feature article by Michael Castleman highlights recent studies on several accessible, generally safe herbs and foods that may support common health conditions. All findings are preliminary (small studies needing replication), but the author notes the remedies are low-risk and worth considering alongside standard care.
- Green Tea (Camellia sinensis) for Urinary Tract Infections (UTIs): Iranian researchers gave 70 women with confirmed UTIs standard antibiotics plus either a placebo or 500 mg green tea capsules daily. After 3 days, the green tea group improved significantly faster and had fewer recurrences within 6 months. Green tea’s catechins have known anti-E. coli effects. The author recommends adding a few daily cups of green tea to antibiotic treatment (repeated in a later section with similar conclusions).
- Cranberry (Vaccinium macrocarpon) for Rheumatoid Arthritis (RA): Brazilian researchers gave 41 women with RA either cranberry juice (500 ml/day) or no treatment. After 90 days, the cranberry group had fewer swollen joints and lower inflammation markers (p=0.05). Cranberries’ antioxidants and anti-inflammatory compounds may also help reduce cardiovascular risk, a common RA complication. Safe and affordable; no miracle cure but potentially helpful.
- Blueberries (Vaccinium angustifolium) for Children’s Cognitive Function: UK researchers at the University of Reading gave 54 children (ages 7–10) either a placebo drink or blueberry juice equivalent to 1.5 cups of fresh berries. Two hours later, the blueberry group showed faster reaction times, better recall, and greater attention on reading tests. Builds on prior evidence that blueberries improve brain blood flow and long-term cognition at any age.
- Lavender (Lavandula spp.) Aromatherapy for Mood and Depression:
- Iranian study: 62 menopausal women wore a bandana with 2 drops of lavender oil (or placebo) for 20 minutes nightly. Lavender improved mood and reduced anxiety beyond placebo effects.
- Chinese study: 60 elderly people with mild–moderate depression received lavender-containing massage, inhalation, or wait-list control. After 10 weeks, 55% of the massage group and 40% of the inhalation group reported mood improvement (vs. 5% on wait-list). Easy to use (inhale or dilute in lotion), but keep away from children and never ingest.
- Boswellia (Boswellia serrata) for Irritable Bowel Syndrome (IBS): Italian researchers had 69 chronic IBS patients follow diet/lifestyle changes; half also took 250 mg boswellia daily. After 6 months, the boswellia group had significantly milder symptoms and fewer doctor visits. Its boswellic acids have anti-inflammatory effects (also helpful for ulcerative colitis). Generally safe, though pregnant women should avoid it.
- Pumpkin Seeds (Cucurbita pepo styriaca) for Benign Prostatic Hyperplasia (BPH): German researchers gave 58 men (ages 60–75) with BPH symptoms 500 mg pumpkin seed extract daily. After 4–12 weeks, most reported fewer nighttime awakenings, weaker symptoms, and overall improvement. Lightly toasted seeds can be eaten whole for similar benefits and add nutty flavor to meals.
- Yarrow (Achillea millefolium) for Early Multiple Sclerosis (MS): Iranian researchers gave 65 people with mild–moderate MS either placebo or yarrow (250 or 500 mg/day) while they continued standard meds. Over 1 year, yarrow groups had fewer relapses, less disability, and slower progression (no dose difference). Contains anti-inflammatory and neuroprotective compounds. Safe in normal doses (may discolor urine at high doses).
Overall Takeaway: The article emphasizes that these botanicals are not replacements for medical care but can be safe, inexpensive adjuncts. Castleman (author of The New Healing Herbs) encourages readers to consult healthcare providers, especially for serious conditions like MS, RA, or severe depression. All studies were published in peer-reviewed journals such as Complementary Therapies in Clinical Practice, Nutrition, European Journal of Nutrition, and Phytomedicine.
