I bought an imp of Energy off of
sinandsalvation a while back. It works wonders!
This year I was diagnosed with breast cancer and went through a lovely, lovely round of treatment - surgery, chemotherapy, radiation and hormone therapy. Result: cancer pwned. Ancillary result: I am low on energy reserves. Hence, Energy oil.
I apply a drop to each chakra point. It smells, incidentally, fresh and lemony/citrussy - almost a "clean lemony laundry detergent" feeling. And boy does it work! It not only gives me energy, it gives me mental energy and motivation. I feel my thinking is sharper and I'm more motivated to do whatever task I have to do. It's like Concentration and Determination in that regard, but for me it gives me that extra boost of vim and vigor.
