Has your doctor or dentist ever asked you what medicines you're taking? If so, have you told them the whole truth? Drug interactions can be dangerous, and you'd be mad to put yourself at risk. But what if you didn't realise you weren't giving them all the facts? All too often, I discover people are taking herbal remedies or supplements - but they have no idea that they 'count' as medicines.
In fact, while millions of people across the world take herbal remedies and supplements every day, many have no idea they can cause side-effects. When I explain to my patients that St John's wort can interact with up to 70% of all prescription drugs; or ginseng can cause dangerous fluctuations in blood-clotting levels if you're taking warfarin; or green tea supplements can interact with pseudoephedrine, taken for colds; or ginkgo biloba can interact with aspirin and warfarin; they're usually stunned.
'Natural' does not mean 'safe'
I'm amazed how many of my patients believe that just because something is 'natural', it must be safe. Deadly nightshade is natural.
Licensed drugs can't be given to the public without reams of evidence, including:
- Whether the drug has a real effect on the condition it's used for (it's important to point out that no medicine works for everyone, but the manufacturers have to jump through lots of hoops relating to 'placebo-controlled' trials - do more people respond to their drug than an inactive pretend tablet - or 'active comparator' trials - does their drug have advantages over current medicines on the market).
- Whether the benefits outweigh the risks.
- How much of the drug is needed for best effect.
- How the drug is manufactured.
- The precise amount of the drug in the tablet.
- How this is monitored and quality controlled.
In the UK, the MHRA (which regulates our medicines) has introduced a 'Traditional Herbal Registration (THR) scheme' which does answer some of these questions. Any THR-marked product must have been produced to a high standard, and the remedies must contain exactly what it says on the packet. All herbal remedies sold in the UK should carry a THR marking on the packet. But there are still lots of gaping holes in the system.
Firstly, if you order herbal remedies over the internet, they may come from outside the UK, where the same regulations don't apply.
And more obvious still, to get this marking you don't actually have to prove your product works. You only have to show your product has been 'traditionally used' for at least 30 years to treat the condition you want to advertise it for.
What doctors recommend
Some of the therapies I recommend regularly include:
Most women suffer from hot flushes around the menopause and many are now worried about the small increased risk of breast cancer which comes with long-term HRT. Red clover isoflavone is a natural oestrogen-like compound. At a dose of 60-80 mg a day, it can help with hot flushes, and it has a good safety record.
St John's wort
This herbal remedy is as good as many medicines available on prescription for treating depression. But a couple of warnings:
- It can interact with other medicines (occasionally seriously).
- If you're considering changing from a prescribed antidepressant to St John's wort, do talk with your GP first.
- I virtually never prescribe antidepressants without also advising talking therapy. Depression can ruin your life - but counselling is a better long-term solution than tablets of any sort.
GOPO for osteoarthritis
Made from the rosehip, GOPO is a product marketed for relief of pain and stiffness for patients with osteoarthritis. Several randomised controlled trials (the gold standard of research) suggest it can reduce pain in patients with osteoarthritis, as well as improving stiffness and general well-being.
Importantly, people with knee and hip osteoarthritis taking GOPO needed significantly fewer strong painkillers compared to people taking placebo.
Glucosamine for osteoarthritis
You can buy glucosamine from a health food store or pharmacy. Taken at a dose of about 1500 mg a day, it may slow down the progression of osteoarthritis. The evidence for benefit isn't very strong and some is inconsistent, but it does have a good safety record so even with a small improvement any benefit is likely to outweigh the risks.
Fish oil - for just about everything!
The Food Standards Agency recommends that we should all be eating at least one portion of oily fish a day to protect our hearts - which gives us about 500 mg a day of the 'long chain' omega-3 fatty acids found in fish oils. If you've had a heart attack, it may be worth increasing that to 1 g a day. Admittedly, recent studies suggest the evidence isn't strong enough to recommend that doctors prescribe supplements for people who've had heart attacks, so you can't get it on the NHS. But population-based studies suggest it certainly won't do any harm and may help.
Unfortunately, most plant-based versions of omega 3 just don't contain enough of the active ingredient to have the same effect.
Omega 3 has also been shown to help with the symptoms of the inflammatory joint problem rheumatoid arthritis. There hasn't been enough research to show the same benefits for osteoarthritis, but it's certainly worth a try if you have rheumatoid arthritis - and it's one of the few supplements I routinely recommend.
Olive oil - outside and in
By now, we all know about the benefits for your heart of eating more olive oil and less butter and animal fat. But olive oil is great for softening earwax, too. A small amount of olive oil applied two to three times a day for four to five days may even soften the wax enough for your body to get rid of it naturally, avoiding the need for syringing.
But a word of caution ...
Alternative therapies can be very tempting. All too often, they offer you the world - or at least a guarantee of success. But do be aware that many of these treatments aren't governed by the same strict regulations as medicines and treatments your doctor can prescribe. So their claims may be based on limited evidence, to say the least.
Call me cynical, but bloodletting was 'traditionally' used to treat every conceivable malady (including blood loss from stab wounds) for well over 30 years back in the mists of time. Anyone for leeches?
