Homeopathic arnica found to be an effective post-operative aid
Arnica is perhaps one of the best known homeopathic remedies, and is generally recommended when there has been some trauma to the body. Arnica is often advised, say, after someone has had a fall to reduce pain and swelling. And another occasion where it might be advised is after surgery. In a recent study the effects of arnica in the post-operative period was compared with a commonly used painkiller – diclofenac. Arnica D4 (D4 denotes the dilution of arnica) was given at a dose 10 pills, taken three times a day. The diclofenac was given at a dose of 50 mg, three times a day. Either of these was administered to 88 people for four days after having surgery for bunion removal (correction of hallux valgus).
The results of this study shows that arnica and diclofenac performed equally well in terms of reducing redness, swelling and heat (all signs of inflammation) in the wound. However, those taking arnica had better mobility, while those taking diclofenac experienced better pain control.
However, the arnica gave rise to significantly fewer side effects: about 20 per cent of those taking diclofenac reported intolerance to the medication, compared to just 4.5 per cent taking arnica. One other advantage of the arnica was that it is cheaper, with the authors noting that arnica is less than half the price of diclofenac.
This study appears to show that arnica has value as a post-operative treatment. Ideally, one might argue, that it would have been better to bit arnica against a placebo. However, as the authors of this study point out, diclofenac has been proven to be superior to placebo for both post-operative use and for “post-traumatic swelling”. Interestingly, the researchers of this study originally intended to compare arnica with placebo, but this study design was refused by the ethic committee on the basis that it would be withholding a known beneficial treatment for post-operative care (diclofenac).
Bearing in mind diclofenac’s proven benefits, the results of this study do seem to support the use of arnica in wound healing and trauma.

This is interesting. I have just finished reading Ernst and Singh’s “Trick or Treatment?”. They are very skeptical as to whether homeopathy offers any benefit above that of placebo.
How many participants were there in the study? Do you know if it will be repeated? Is there a summary of the study available online for us to read?

The number of people in the study has already been stated above.
I do not know if this study is to be repeated.
A summary of the study is available on-line (see the Jan 2008 issue of the journal).

I note that D4 implies dilution by 10 repeated 4times i.e. 1:10000 dilution. Also the dosage taken 3times per day is 10pillules which seems alot (vs 50mg of diclofenac 3times a day).
Arguably what might be happening here is that the raw ingredient Arnica is being given in a dosage much much larger than a typical homeopathic concentrations (which can often be absolutely huge orders of magnitude of dilution e.g. C6 is 10tothepower12)
From original paper I cannot see what volume a pilule might be or how much raw Arnica is started with so it is hard to calculate what the actual dosage of Arnica is?
Any thoughts Dr B?
(For the record I have nothing against naturally occurring ingredients. Some of them are great e.g. Aspirin)

I can only get hold of the abstract.
Is diclofenac actually prescribed for any of the symptoms that arnica was equal to it in? I thought it was mainly prescribed for the pain in these circumstances. Not really a good comparator, and no placebo group. Any correction for multiple comparisons? (though I’m not sure how that would work when a positive result is a non significant difference…)
I’m sure I read also that diclofenac can delay wound healing.
Also the two groups got different numbers of pills - which could have a differential placebo effect and cause problems with blinding. Were any of these problems addressed in the paper?

I don’t understand - if arnica is used as a herbal remedy for bruising and trauma, then homeopathic arnica should have the opposite effect. Not that D4 is particularly potent by homeopathic standards.

I am a homeopathic user. I would not go on using the stuff if it did not help. I have observed swelling on bumps go down rapidly following arnica in children. This is not a placebo effect. As a result of using homeopathic medicines (in babies and the cat- not placebo effect) I have avoided my children (now in their 20s) taking antibiotics. Asthma has been sorted and other breathing problems (severe enough to cause hospitalisation prior to homeopathic input)
Other people are not fools - they would not continue seeking hoempathic treatment if it didn’t help. Plenty of conventional medicine doesn’t work and gives nasty side effects.

Herbalists use arnica tincture and ointment. The arnica ointment I bought from a homoeopathic chemist was straight arnica ointment, not it homoeopathic dilutions.
I’d certainly use arnica for cuts and bruising again but I see no need to use it in homoeopathic quantities. How do the two compare against each other? That, surely, is the trial that needs to be carried out.

I am due to have surgery next week but I have MS for which I take quite a lot of medication. Is it safe to take Arnica?
