Fenchol
Fenchol is a cool pine-and-herb smell with a little lemon and camphor behind it. Think crushed basil next to a conifer branch, not cookie dough and not black pepper. Another name you will see on the same line is fenchyl alcohol. Older notes sometimes say 2-fenchanol. Those are the same compound.
The usual formula given for fenchol is C10H18O. Some older pages printed C10H16. Treat that as a slip meant for the hydrocarbon cousins, not a second official fenchol.
Basil, fennel, eucalyptus, and some citrus plants are how people meet the smell outside flower. Candle, soap, and flavor work use the name for that same pine-citrus snap. On flower reports fenchol is almost always a small line, not the first word next to myrcene or limonene.
OG Kush, Banana Kush, and Banana OG are the strain names that come up with it most often. That is common talk, not a closed club. Two packs can both list fenchol and still be different plants.
Borneol is the lookalike: another camphor-pine alcohol, not the same molecule. Pinene is straighter pine resin. If a report lists fenchol next to those, it is describing a cool-wood mix, not proving one family.
The useful part is still the smell: basil, pine, and a little camphor. A forest-cleaner or herbal-soap brand on a bag is not the same thing as a printed fenchol line.
Fenchol rarely leads a report. When it is there, it is a background cool-wood note sitting under louder words like myrcene or limonene.
