10-epi-γ-Eudesmol synthase (EC 4.2.3.84) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate diphosphate-lyase (10-epi-γ-eudesmol-forming).{{cite journal | vauthors = Yu F, Harada H, Yamasaki K, Okamoto S, Hirase S, Tanaka Y, Misawa N, Utsumi R | title = Isolation and functional characterization of a beta-eudesmol synthase, a new sesquiterpene synthase from Zingiber zerumbet Smith | journal = FEBS Letters | volume = 582 | issue = 5 | pages = 565–72 | date = March 2008 | pmid = 18242187 | doi = 10.1016/j.febslet.2008.01.020 | doi-access = free }} This enzyme catalyses the following chemical reaction:

: (2E,6E)-farnesyl diphosphate + H₂O $\backslash rightleftharpoons$ 10-epi-γ-eudesmol + diphosphate

The recombinant enzyme from ginger (Zingiber zerumbet) forms β-eudesmol, 10-epi-γ-eudesmol, α-eudesmol and aristolene.
