The herbal pharmacy
Herbs have been used as medicine since time immemorial and even now four in ten drugs derive from natural remedies. But which are best for older people – and how safe are they?

Turmeric
(curcuma longa)
What is it?
Turmeric is the rhizome of a plant native to India and southeast Asia. Part of the ginger family, it gives a vibrant yellow hue to food and has potent anti-inflammatory properties.
The evidence
A review of studies on curcumin (a key ingredient) for knee arthritis in 2021 found it improved pain and function compared to a placebo, with results similar to anti-inflammatory drugs like ibuprofen and naproxen.
Other research suggests turmeric may help prevent heart disease, protect the nervous system and slow neurodegenerative conditions. It also shows promise in repairing cell damage, regulating blood sugar levels and preventing age-related muscle loss. One 2024 study suggests it may be a useful add-on to blood pressure-lowering drugs.
How it works
Turmeric contains curcuminoids, natural anti-inflammatory plant compounds that are thought to block proteins that trigger inflammation, reduce levels of harmful chemicals produced during inflammation and activate pathways that calm it. They also reduce enzymes that cause pain. However, curcumin is hard to absorb and breaks down quickly. ‘Look for a formulation with a minimum daily dose of 700mg curcuminoids,’ advises Kevin Leivers, pharmacist and founder of online natural products firm thenakedpharmacy.com.
