Each corner and line-end is a carbon atom. The yellow S marks sulphur, the atom that gives this whole family its powerful smell. SavouryUmamiSulphurousMild garlic About What is Prenyl methyl sulphide? Prenyl methyl sulphide pairs the prenyl group with a small methyl group across a single sulphur atom. It is one of the softer members of the family. Rather than a sharp skunk or garlic hit, it adds a savoury, umami quality, a bit like the background depth in a slow-cooked stock. What the research says The Science Milder sulphur compounds like this one help round out a cultivar’s overall smell. They are easy to miss on their own but add richness to the whole. As with the rest of the family, the research so far is about aroma. Any effect in the body is unknown.

Good to know A Note on Safety Prenyl methyl sulphide is an aroma compound, present in cannabis in trace amounts. It is not a medicine and has no dose of its own. What matters for you is the whole product and how it is prescribed. Always choose and adjust your medicine with your prescriber and pharmacist, never by smell alone. Questions Prenyl methyl sulphide: Common Questions What does umami mean here? Umami is the savoury, moreish taste in foods like broth, mushrooms and parmesan. Prenyl methyl sulphide adds a smell with that same savoury depth. Is it as strong as the skunk molecule? No. It is one of the gentler compounds in the group, so it tends to sit in the background rather than take over.
