And yet I STILL didn't order the Starter Kit! My husband got it for me for our Anniversary. After getting the "Think Dirty" app (get it now) and seeing how many toxins lived in my home, I WAS SHOCKED. I started replacing aspects of my home with the oils and extras in the YL kit - our home is now mostly toxin free and we have made the switch to cleaner living through these products. I have seen real health benefits: including lavender helping my insomnia, peppermint taking away my migraines, and digize curing my car sickness. But the only way to truly enjoy the health benefits is trying the PSK for yourself (& don't worry! I will be there for you every step of the way!).
