Most discussions about herbal remedies spend a lot of time on whether herbs work in general, which is not really a useful question. The useful question is: does this specific herb work for this specific problem, and what does the evidence actually show? The answer changes considerably depending on the ailment.
For some of the most common health concerns among adults over 50, including joint pain, disrupted sleep, digestive discomfort, colds, and chronic stress, there are herbs with meaningful clinical research behind them. For other popular uses, the evidence is thin or mixed. Knowing which is which helps you make better decisions about where to invest your time and money, especially if it’s in holistic wellness.
This article takes an ailment-first approach, mapping the best-evidenced herbal options to the conditions they are most likely to help. For a broader look at how to evaluate any herb's safety and drug interaction risks, our companion guide to whether herbal remedies are safe and effective covers that ground in detail.
The long story, short, is that herbal remedies can help treat & manage certain types of chronic pain.
Joint Pain and Inflammation? Where Herbs are Most Effective
Joint pain is probably the area where herbal medicine has accumulated the most consistent clinical evidence, and it is also one of the most relevant concerns for adults in their 50s and beyond. Two herbs stand out.
Turmeric (curcumin) has been evaluated in over a dozen randomised controlled trials for osteoarthritis. A 2021 systematic review published in the Journal of Medicinal Food pooled results from multiple trials and found curcumin supplementation produced statistically significant reductions in pain and improvement in physical function compared to placebo. Some trials have found curcumin comparable to ibuprofen for pain reduction, with a more favourable gastrointestinal side effect profile. Preparation matters considerably: curcumin absorbs poorly without piperine (black pepper extract), so look for formulations that include it.
Boswellia serrata, the resin of the Indian frankincense tree, has a similarly solid evidence base for joint conditions. A key clinical trial published in the International Journal of Medical Sciences found significant improvements in pain and physical function in osteoarthritis patients over 90 days. Boswellia works through a different anti-inflammatory mechanism than NSAIDs, inhibiting 5-lipoxygenase rather than cyclooxygenase enzymes, which may explain why some people who respond poorly to conventional anti-inflammatories do better with it.
Ginger also has modest but positive evidence for joint pain, particularly in osteoarthritis of the knee. It works primarily through anti-inflammatory mechanisms and carries a reasonable safety profile. Our guide to natural remedies for chronic pain goes deeper on these options and includes preparation guidance for each.
Trouble Sleeping? Modest but Meaningful Evidence
Sleep problems are extremely common among older adults, and pharmaceutical sleep aids carry significant risks for this age group, including next-day cognitive impairment, fall risk, and dependence. Herbal options with clinical evidence are therefore particularly worth knowing about.
Valerian root is the most extensively studied herbal sleep remedy. The evidence is mixed overall, but several well-designed trials have found valerian to improve sleep quality and reduce time to sleep onset. A meta-analysis published in the American Journal of Medicine reviewing 16 studies concluded that valerian may improve sleep quality without producing side effects. Valerian's proposed mechanism involves GABA receptor activity, similar to the pathway targeted by benzodiazepine sleep medications, but without the receptor-binding affinity that produces dependence.
Chamomile has a long traditional use for relaxation and sleep, and some clinical evidence supports mild anxiolytic effects. A 2017 randomised trial in the Phytomedicine journal found chamomile extract improved sleep quality measures in older adults compared to placebo over a 28-day period. Chamomile is well-tolerated in most adults, though those with ragweed allergies should avoid it. For practical preparation, a well-made chamomile tea or concentrated extract both deliver meaningful amounts of the relevant active compounds.
Passionflower (Passiflora incarnata) is less well-known but has clinical trial support for mild anxiety and sleep difficulties. A small but well-controlled New Zealand trial published in Phytotherapy Research found that passionflower tea improved subjective sleep quality over a one-week period. It is generally considered safe and well-tolerated.
Digestive Complaints: Some of the Clearest Evidence in Herbal Medicine
Herbal medicine has a particularly strong track record for digestive complaints, and this is one area where the evidence is genuinely clear for specific conditions.
Ginger for nausea has robust support across multiple populations and contexts. Clinical trials have demonstrated effectiveness for morning sickness during pregnancy, post-operative nausea, and motion sickness. A systematic review in the Obstetrics and Gynecology journal found ginger significantly reduced nausea severity and episodes compared to placebo. Fresh ginger, ginger tea, and standardised extracts have all been tested; the evidence does not strongly favour one preparation over another.
Peppermint oil for irritable bowel syndrome (IBS) has consistently positive evidence from randomised trials. A 2014 meta-analysis in the Journal of Clinical Gastroenterology covering nine trials found enteric-coated peppermint oil significantly reduced total IBS symptoms and abdominal pain compared to placebo. Enteric coating is important here: it prevents the oil from releasing in the stomach (which causes heartburn) and allows it to act in the intestines where it is needed.
Fennel, chamomile, and lemon balm have traditional use for bloating and general digestive discomfort. The clinical evidence for these is more limited than for ginger and peppermint, but they carry low risk and have been used safely for centuries in both culinary and medicinal contexts. Our herbal medicine recipes guide includes simple preparations for several of these digestive herbs that you can make at home.
Immune Support and Colds: Modest Evidence Worth Understanding
Cold and flu season prompts a lot of questions about herbal immune support, and the evidence here is more nuanced than many products suggest.
Echinacea is the most studied herb for immune support, and the research is genuinely mixed. A major 2015 Cochrane review of 24 randomised trials concluded that some echinacea preparations may modestly reduce the incidence or duration of the common cold, but results varied considerably by preparation, species, and dosing. The most consistent finding across better-quality trials is a modest reduction in cold duration when echinacea is taken at the onset of symptoms. Echinacea is generally safe for short-term use in healthy adults; those with autoimmune conditions or on immunosuppressant medications should avoid it.
Elderberry (Sambucus nigra) has attracted increasing research attention. A 2016 randomised trial published in Nutrients found that elderberry supplementation reduced the duration and severity of colds in air travellers. A 2019 meta-analysis in Complementary Therapies in Medicine concluded elderberry supplementation substantially reduced upper respiratory symptoms. The mechanism appears to involve flavonoid compounds that inhibit virus cell entry and stimulate immune cytokine production. The evidence base is still smaller than for echinacea but is growing.
Garlic has antimicrobial properties well-documented in laboratory studies, and there is some clinical evidence for a modest reduction in cold frequency with regular supplementation. A single large randomised trial found garlic supplementation reduced cold incidence over a 12-week period, but the evidence has not been replicated at scale. Eating garlic as food remains the most straightforward approach.
Stress, Anxiety, and Cognitive Function
Chronic stress is increasingly recognised as a significant contributor to a range of health problems, and several herbs have clinically meaningful evidence for supporting the stress response.
Ashwagandha remains one of the best-studied adaptogens for stress and anxiety, with multiple randomised trials showing reductions in cortisol and perceived stress scores. Rhodiola rosea has a smaller but positive evidence base for fatigue and stress resilience, particularly in people experiencing burnout from occupational or physical demands.
Ginkgo biloba for cognitive support and memory has a more complicated evidence picture. Older meta-analyses were modestly positive, suggesting delayed progression of dementia symptoms. However, a large NCCIH-funded randomised trial (the GEM study) found no significant effect on dementia prevention in cognitively normal older adults. Ginkgo may have a role for those already showing mild cognitive changes, but it is not a prevention strategy for healthy adults.

Matching the Herb to the Ailment: A Practical Summary
The pattern across these ailments reveals something important. Herbal remedies tend to work best when used for conditions that conventional medicine also finds difficult to treat cleanly with single-target pharmaceutical drugs: chronic low-grade inflammation, intermittent sleep disturbances, functional digestive symptoms, and stress-related complaints. These are conditions defined by biological complexity, and plant compounds with multiple modes of action often prove valuable precisely because they act on several pathways simultaneously.
Herbal remedies are less likely to substitute for modern medicine in acute situations, in serious or progressive disease, or where a specific, targeted pharmaceutical mechanism is critical. Understanding which category your health concern falls into helps you use herbal medicine as the complementary tool it works best as, rather than as a replacement for care that genuinely requires something else.
How to Get the Most From Herbal Medicine
Using herbs effectively for common ailments requires knowing more than just which plants to reach for. It requires understanding the preparation that delivers the relevant active compounds, the dose that matches the clinical evidence, and the specific situations where caution is warranted. That depth of knowledge, built from both the accumulated wisdom of herbal practice and the testing rigor of modern research, is what allows plant medicine to be genuinely useful rather than simply hopeful.
A comprehensive herbal medicine book provides exactly that kind of grounded, condition-specific guidance. It connects the traditional knowledge of how to grow, prepare, and use medicinal plants with the modern evidence that tells you which of those uses are most reliably supported. For anyone looking to use herbal medicine seriously and safely, that kind of resource is where to start.
