Essential oils in Shanghai

I've been meaning to pop by these shops to check out their essential oils offering. I'm by no means an expert in this field but have always wanted to learn more about aromatherapy since I believe in its healing properties.

• Herbal shop on Shaoxing lu, appr halfway between the Vienna Cafe and Shanxi nan lu (opposite side Vienna Cafe)
• Fumin lu 152 (they sell dried herbs, and I think I remember essential oils as well)
• NUZI on Taikang lu (No.30, Lane 248 Taikang Lu, near Sinan Lu), they sell products from New Zealand http://www.nuzi.com.cn/
