Where can I buy authentic and high quality essential oils for aromatherapy in Manila?

I use this organic brand called Milea. I am not sure if they already have a branch here in Manila but i purchase products from them online. You can purchase different organic products from soap, oils and even makeups. Their essential oils are priced P285 per bottle (100ml). They have a wide selection of aromatics and they claim that their products are from 100% pure oil from plants. Here's a link to their website: http://www.milea.ph/essential-oils-30ml/
