I’ve been infusing these organic herbs (I’ve collected from my mom’s garden) with vegetable oils for about 1 week now. I got the idea from Pure Skin: Organic Beauty Basics by Barabara Close.
You can read my little review of her book on my “Resources” page. 
I chose some light vegetables oils such as grape seed and sunflower. You can also use avocado, sweet almond, or jojoba oil as well.
I used two different brands of grapeseed oil. Basso brand is much more green then Trader Joe’s version. I infused them with dried and powdered kaffir leaves and gotu kola (Tiger grass). Both are great herbs not just for eating but for skincare as well.
For the sunflower oil, I infused with calendula flowers (the head).
This is just an experiment, so I made a small batch and used old spice jars to fill them in. Although I don’t have it in my photo, I did cover each glass jar with a cotton fabric. This helps the air to circulate without making the oils dusty or dirty.
