Following last week's spotlight on Fairtrade and food, this week we turn our 'You ask, they answer' series to look at organics and beauty. For the next four days, ethical skin and body care products firm Neal's Yard Remedies will be doing its best to answer your questions below.

Neal's Yard Remedies started life back in 1981, with a focus on using natural herbs for health and beauty. Since then, it's grown to 38 stores across the country, and started a range of green initiatives, including a number of certified organic products, bought carbon offsets to reduce its emissions and encouraged customers to recycle and reuse old packaging.

This is your chance to grill them: from the controversy surrounding the chain's removal of a homeopathic malaria remedy to the benefits and reasons to switch to organic beauty products.

To get the debate rolling, just post your questions below.
