Swapping Out Litsea Cubeba: Match by Citral Weight
Your recipe calls for litsea cubeba and the bottle is empty. It is tempting to reach for another lemon-scented oil and swap drop for drop, but the oils behind that lemon smell vary by a factor of ten in how much citral they carry. A better swap starts with a gram scale and one question: what was litsea doing in this recipe?

We describe litsea cubeba as intense, sweet and lemon-bright, a lemon-drop sparkle with a soft fruity, floral roundness. That is really three jobs at once: the sharp citral lemon, the sweetness behind it, and the way it sits at the top of a blend. Composition data can speak to the first one. It cannot tell us how any oil behaves in your wax, soap or lotion, so we will not pretend to rank substitutes on staying power. Instead, we can match the citral by weight, which is the part you can calculate.
The candidates, in plain terms
- Lemon myrtle is the closest on paper. A review of its chemistry describes citral-type leaf oils at roughly 80% citral or more, similar to the top of the litsea range.
- Lemongrass is the familiar workhorse. Eleven commercial Brazilian samples of dried leaf ran from about 41% to 75% citral, so the lot matters a great deal.
- Lemon verbena smells lovely but sits lower in citral (one Portuguese study found about 34% to 37%), and IFRA says verbena oil should not be used as a fragrance ingredient because of its sensitising and phototoxic potential. See our verbena comparison.
- Cold-pressed lemon is a limonene oil with only a trace of citral, about 4.4% in one review table. It is a lovely lemon, just a different one, and pressed peel oil has its own IFRA limit because of phototoxicity.
Litsea itself ranged from about 79% to 87% citral in laboratory distillates from eight sites in China, which is the reference line for the sums below.
The swap, worked in grams
Say a formula uses 2.0 g of a litsea oil at 80% citral. That figure is illustrative, taken from inside the published range, not a statement about our oil. It supplies 1.6 g of citral. To supply the same citral from each substitute, divide 1.6 by the substitute's citral fraction:
| Substitute (illustrative citral) | Grams needed | Versus litsea by weight |
|---|---|---|
| Lemon myrtle at 90% | 1.78 g | 0.89 to 1 |
| Lemongrass at 60% | 2.67 g | 1.33 to 1 |
| Lemongrass at 41% | 3.9 g | about 2 to 1 |
| Cold-pressed lemon at 4.4% | 36 g | about 18 to 1 |
The last row is the most telling. Cold-pressed lemon cannot supply the citral note at any sensible dose. It supplies a different, limonene-led lemon, and that is a reason to choose it for what it is rather than as a stand-in. For the others, matching citral matches one molecule; the rest of each oil differs, so the finished scent will too. Reasoning from composition, lemon myrtle and lemongrass are the closest swaps.
Drops are the wrong unit here as well. The Certificate of Analysis we publish for one litsea batch gives a relative density of 0.883, about 20 drops per ml, but other oils differ in density and droppers vary. Weigh your oils, start from the weights above, then run a small test batch.
Matching the swap to the job
- A candle, diffuser or room scent for yourself: lemon myrtle or lemongrass from a craft or aromatherapy supplier. Ask them for a GC-MS report on the lot so you can run the table with the real citral number.
- Anything made for sale or for skin: the IFRA citral caps decide the ceiling, whichever oil you choose, so a cosmetic chemist or regulatory consultant should check the sum. Our IFRA article shows how.
- Pregnancy, children or pets in the household: check with a physician or pharmacist before using any of these oils. We sell an external cosmetic oil and do not offer guidance for those situations.
If a plain lemon peel smell is all you want, lemon oil from a grocery or craft supplier is the right oil, not a compromise, and litsea against lemon explains how they differ. The citral comparison lays the oils side by side. We sell litsea cubeba only, so the substitutes come from a supply shop.
The best swap is the one you have measured: pick the oil for the job, weigh it, and test a small batch before committing a big one.
