Is this sentence correct?

Your sentence is grammatically correct:

“There is a mythical plant whose sap works as the elixir of youth.”

The relative pronoun “whose” is most commonly used for people, but it is also perfectly acceptable for animals and things—especially when indicating possession.

In your sentence, “whose sap” refers to “the sap of the plant,” which is a standard and natural use. While some older grammar guides preferred avoiding “whose” for inanimate objects, modern English usage accepts it widely, especially when the alternative (like “the sap of which”) would sound awkward or overly formal.

So your sentence is both correct and stylistically natural.
