You can buy a homeopathic birthing kit from helios ( I got mine on ebay). The booklet explains the remedies. You take 6c for long term conditions and 30c for acute conditions, ie just after an accident/shock etc. The birthing kit remedies are 200c as they are very acute!
essential oils I would recommend Tisserand, or Lothian Herbs or Purple Flame. You need to be careful buying them as they need to be pure and not contain any synthetic fragrances ( like ones for burning in pots or adding to pot pourri.
I am going to mix up Lavender, Jasmine and Rose in some shea butter oil for labour, you can use extra virgin olive oil or grapeseed. Lavender is good for bruising, lowering blood pressue, pain relief amongst many other things, jasmine is a powerful uterine stimulator, and rose is great for all women's sexual organs, it's calming, relaxing and lots of other properties too.
With essential oils remember less is more - don't add more thinking it will be more effective - they are VERY POWERFUL and can have a detrimental effect if used in large quantities. It would be a good idea for you to read up on them a bit maybe. You can use lavender just now - I add it to my body moisturiser, or add to an eggcup full of milk and place in bath swishing water well before you get in. Don't use jasmine just now though as you aren't 'cooked' yet!
