Litsea Cubeba Substitutes: Swap by Citral Weight, Not Drops
If you cannot get litsea cubeba oil, do not swap another lemon-scented oil in drop for drop. The oils differ in citral content by a factor of more than ten, differ in density, and two of the usual candidates carry a documented restriction. Work out what litsea was doing in your recipe, then replace that by weight and test a small batch.

Litsea is sold here as a top note, described in the shop copy as intense, sweet and lemon-bright with a soft fruity, floral roundness. Three different jobs hide in that: the citral lemon note, the sweetness behind it, and how long the top note holds. We have no test data on how long it holds in any product, so I will not rank substitutes on tenacity. What can be worked out from the literature is the citral part, and that is where the swap arithmetic starts.
Step two: the candidates, with the documented catch for each
| Candidate | Citral (neral + geranial), as published | Documented restriction or hazard (IFRA_STD_021 limits citral itself in a finished product) |
|---|---|---|
| Litsea cubeba (reference) | 78.7% to 87.4% (8 Chinese samples; Si, 2012) | IFRA citral Standard, a restriction (Amendment 49, 2020) |
| Lemongrass | 40.7% to 75.4% (11 commercial Brazilian samples; Barbosa, 2008); 89.2% in one Nepal leaf oil (Dangol, 2023) | Same IFRA citral Standard |
| Lemon myrtle | 80.0% to 96.0% (Southwell, 2021 review) | Same IFRA citral Standard; the review recommends topical use below 1% in a topical formulation and cites a review advising restriction during pregnancy |
| Lemon verbena | 34.0% to 37.3% in one Portuguese batch (Sprea, 2023) | IFRA: verbena oil from Lippia citriodora should not be used as a fragrance ingredient (sensitising and phototoxic potential); absolutes restricted |
| Melissa | about 11% to 79% in the single studies listed by Petrisor, 2022; some oils have none | Same IFRA citral Standard; adulteration concern (see the melissa post) |
| Cold-pressed lemon peel | geranial 2.9% plus neral 1.5% = 4.4%, with limonene 69.9% (Klimek-Szczykutowicz, 2020 review) | IFRA Standard on citrus oils and other furocoumarin-containing oils names cold-pressed lemon oil: phototoxicity |
The IFRA verbena Standard (IFRA_STD_083, Amendment 49) is explicit: verbena oils from Lippia citriodora Kunth "should not be used as a fragrance ingredient, based on its sensitizing and phototoxic potential," while verbena absolutes are allowed up to category limits such as 0.69% in Category 4 (IFRA, 2020a). The citrus Standard (IFRA_STD_089) restricts lemon oil cold pressed, with a Bergapten (5-MOP) ceiling of 0.0015% (15 ppm) in the finished product on skin exposed to UV light for most categories, and says that where several furocoumarin oils are present their percentages of their limits must sum to no more than 100 (IFRA, 2020b). The citral Standard (IFRA_STD_021) caps citral per product category, 0.60% in Category 4 and 0.15% in Categories 5A to 5C (IFRA, 2020c). Those are the 2020 texts as read on 28 October 2026; amendments change them, and a cosmetic chemist or regulatory consultant should check the current standard before you sell anything. Whether an oil's citral counts toward a given cap is for that assessor to work out. For a home candle or diffuser they are guidance rather than law, but they show which oils the industry's safety panel flagged.
Step three: replace by weight, with the sum shown
Suppose a formula uses 2.0 g of a litsea oil at 80% citral, an illustrative figure from inside Si's range, not a figure for our oil. That is 1.6 g of citral. To supply the same citral by weight:
| Substitute (illustrative citral fraction) | Grams for 1.6 g citral | Ratio to litsea by weight |
|---|---|---|
| Lemon myrtle at 90% | 1.6 / 0.90 = 1.78 g | 0.89 to 1 |
| Lemongrass at 60% | 1.6 / 0.60 = 2.67 g | 1.33 to 1 |
| Lemongrass at 40.7% (Barbosa low) | 1.6 / 0.407 = 3.93 g | 1.97 to 1 |
| Verbena at 35% (if a supplier documents it for your use) | 1.6 / 0.35 = 4.57 g | 2.29 to 1 |
| Cold-pressed lemon at 4.4% | 1.6 / 0.044 = 36.4 g | 18.2 to 1 |
The last line is the point of the table. Cold-pressed lemon cannot supply the citral note at any sensible load; it supplies a limonene-led lemon note that is a different smell, with the phototoxicity limit above. For the rest, matching citral by weight only matches one molecule. The remainder of each oil (limonene, myrcene, cineole, caryophyllene oxide, depending on the oil) is different, so the finished smell will differ. Reasoning from composition, the closest swaps are lemon myrtle and lemongrass; I have no test data on how any of them behaves in wax, soap or lotion, and the shop's statement that litsea is used slightly heavier than synthetic fragrance in cold process soap is the shop's, not a measured result.
Drops are the wrong unit for another reason. We know the relative density only for the litsea batch on our COA, 0.883, which gives about 20 drops per ml and 591 drops per ounce; droppers vary and other oils differ in density, and I fetched no density figure for them. Weigh on a gram scale, using the weights above as starting points, then run a small test batch and a patch test, because we have not made or tested any of these swaps.
Which swap for which job
- A lemon-bright candle, diffuser or room scent for your own use: lemon myrtle or lemongrass, bought from a craft or aromatherapy supplier who will give a GC-MS report for the lot in writing. Ask for the citral percentage so you can run the table above on the real number.
- Anything that goes on skin and is sold: the IFRA numbers above decide the ceiling, not the recipe. Talk to a cosmetic chemist or regulatory consultant. If you are pregnant, or making for someone who is, or for a child, ask a physician or pharmacist first; I will not call any of these oils safe for those groups.
- A "lemon verbena" oil: check what the label says and what the seller can document against the IFRA prohibition above; the comparison with litsea is in our verbena comparison.
- Melissa: a substitute only for itself, with its own concerns in the melissa post.
When litsea is not the one to chase
If what you want is a plain lemon scent, lemon oil is the right oil and not a compromise; see litsea against lemon for how they differ, and keep the phototoxicity limit in view. If your recipe depends on citral, the spread between lots and between oils in the citral table is why you should buy on a GC-MS report. Lemon myrtle has its own page in the lemon myrtle comparison, and lemongrass in the lemongrass comparison.
We sell litsea cubeba oil only, none of the substitutes named here, so the supply shop is where the others come from. Whatever you choose, citral oils belong well down in a carrier and behind a patch test.
