Arnica in a cream works quiet well it labour, also clary sage oil is the same as it helps to relax the muscles i found clary sage a magical treat and my mum used arnica and said the same. i just added a few drops of clairy sage to baby oil and rubbed it in and you can buy arnica rub in a tub.

Good luck sweety

I was given some stuff to put in my bath after birth by my midwives, It made the water green but I can't remember what it is called so I'm sorry to be of so little help.  I don't know if you have any midwives in your area that you can contact.  I can't see them not giving you the info even if you are not a patient.

Arnica is not recommended for use during pregnancy or when breastfeeding.  There are some chemicals in it (natural of course) that can cause problems with the blood.  Any midwife who recommends it should be struck off.  I had a massive bruise with my 4th pregnancy that kept rebruising and asked my pharmacist if I could try it, and he said 'oh no, you could really cause problems during labour with excessive bleeding'  A better natural healing aid is papaya or paw paw.  Massage it onto the affected area and it helps to break bruising up.

Espom salts for the bath will help with vaginal tearing.  The other thing I used to prevent further damage when going to the toilet was lanonlin.  I'd apply it to the tear before and after weeing and it protected the tear from the urine sting and also kept the area nice and moisturised so that it didn't scab up, but healed much more smoothly.  It is also great for nipple complaints too.
