Does anyone know of a remedy that I could try for blocked fallopian tubes, with scarring. Thanks

Silica was the normal standard for this.
Possibly followed by Fluor Acid for the scarring.

It may be that Silica is often indicated in this kind of problem - but taking Silica without having had your case taken and analysed properly is guessing. And it could potentially add to your problem if it's not the right remedy for you.

If you are new to homeopathy - please know that it's not easy to practise. And we don't prescribe on disease names. If you want sound care, you need to find a homeopath who can take a full case and provide proper follow up as your case unfolds.

There are many homeopaths in UK. Which area are you located? Perhaps someone here can recommend someone to you.

to take the full case , but where the potencies used are in the 3x - 6x area there is a broad band effect and it is unlikely that any harm would occur.
