Citronellas are a popular plant in Europe.

But the plant has also been known to make people feel sick, and one study found that its use has led to a drop in depression among people in the Netherlands.

The plant is one of a few types of plants that are classified as “cultivars,” which means they’re used to produce an edible product.

When Citronelliaceae is used recreationally, it can be a treat or a stimulant, but there’s some evidence that it’s also addictive.

In a 2015 study, researchers at the University of Southampton found that people who were exposed to the drug citalopram experienced a marked reduction in their mood.

So, if you want to get your fix, try one of the more popular Citronels—or even more popular ones, like kratom, or kiwi fruit.
