Love-Me Tea

The tea is given to Sierra by a Chinese woman in Chinese Fake-Out after Sierra crashed through her roof and explained to the old woman her problem about her unrequited love for Cody. The woman gives her the teabag with the words: "You need Love Tea. More you drink, more he love." Sierra continues to drink her tea in between each of the meals of the eating challenge in hopes it will work. She mentions it again at the end of A Chinese Lesson "Cody's in first class with me and my love-me tea" and once more drinks from her tea pot when Blaineley points out that Cody has repeatedly tried to vote her off. She brews another batch in first class which she splashes on herself like a cologne (likely trying to speed up the effects) and tosses the pot aside, breaking it. But Cody has an allergic reaction to the tea.

In African Lying Society, Sierra brews some more tea in a glass cup after breaking her teapot. Sierra reveals her plan in the confessional that instead of her drinking it, she's trying a different tactic of having Cody drink it instead. Sierra believes it is working (though is oblivious to the fact that his "compliments" and etc. were simply unintelligable moans.) As Sierra continues to feed Cody the Love-Me Tea, he suffers hallucinations and goes into a comatose state.

In Awww, Drumheller, Sierra likely ran out during the African Lying Society, but whatever was left of it if any, was likely destroyed in the explosion.
