-"The leaves of the plant are linear to lanceolate, 3–15 cm (1.2–5.9 in) long and 0.3–3 cm (0.1–1.2 in) broad, with a lobed margin; they give off a sweet odor, especially when crushed... The aromatic leaves (fresh or dried) are also used to make a tea. The Canadian author Catharine Parr Traill includes it in her book The Female Emigrant's Guide in a list of substitutes for China tea. When boiled, she notes, it has a slightly resinous taste, with a bitter flavour, that is not very unpleasant." [[https://en.wikipedia.org/wiki/Comptonia_peregrina|wikipedia]]

-"Essential oil extracted from Comptonia peregrina (L.) Coulter (sweet fern) harvested in the lake Saint-Jean area (Québec) has been analysed using GC-MS and Kovats indices techniques. The main identified products are (E)-2-hexenal (16.8–19%), β-caryophyllene (10.7-13.3%), 1,8-cineole (9-10%), myrcene (5-7%), and linalol (4-5.4%)." \\

 The essential oil contained many monoterpenoids like α-pinene (3.1%), myrcene (7.3%), 1,8-cineole (9.7%), and γ-terpinene (4.2%) as well as sesquiterpenoids like β-caryophyllene (27.0%) and α-humulene (1.3%), α-/β-selinene, γ/δ-cadinene, and (E)-nerolidol (2.3%) as main components. \\

-"Comptonia peregrina (L.) Coulter, a native plant from Canada used in traditional medicine against cancer, was extracted by hydrodistillation. Two fractions were collected, one over 0–30 min and one over 30–60 min, to assess the influence of time of hydrodistillation on the composition of essential oil. The chemical composition of these two extracts was determined by GC and GC-MS analyses. Fifty five components were identified: β-caryophyllene (23.69% and 15.16%) and α-humulene (9.67% and 7.43%) were the major components in the 0–30 min and 30–60 min fractions, respectively, while β-myrcene was detected in a higher amount in the 0–30 min fraction (12.58%) than in the 30–60 min fraction (0.15%)." \\
