Farnesene in strain profiles: compound without mammal study

• In the pharmacy list. Does not lead in any of the 85 strains, although profile databases mention it in 11 of them. This is the content of this page, not a gap.
• Evidence. 2 works from 2010 to 2025, all on animals or in cell culture, none on patients consuming the herb.
• Temperature. no data, while the measurement condition determines whether the number means anything.
• What we do not provide. Percentage share in the profile, because the denominator in sources varies and the numbers are not comparable between strains.

What is farnesene and where does it occur outside of cannabis?

Farnesene is a sesquiterpene with the formula C15H24 and a molecular weight of 204.35, which means it is one and a half times larger than monoterpenes like limonene. Outside of cannabis, it has primarily been described in the world of aphids and the plants they inhabit. PubChem lists this compound under the name (E)-beta-farnesene and number 5281517.

The systematic name is (6E)-7,11-dimethyl-3-methylidenedodeca-1,6,10-triene. The public card for this compound is poor in the measurement section: in the physical description column, there is just one word, liquid. Myrcene has four boiling point entries in the same registry from four institutions, while farnesene has none.

Under one name, there are actually several different molecules. Farnesene occurs in both alpha and beta forms, and each has variants differing in the position of the double bond. The profile databases from which our terpene set comes simply write farnesene and do not specify the isomer. The evidence material we have, however, clearly pertains to the (E)-beta form. As long as the composition description does not specify which molecule is indicated, conclusions from studies on one of them cannot be transferred to the contents of the package.

The best-documented place for this compound outside of cannabis is in insect communication. Aphids release (E)-beta-farnesene as an alarm signal, and the plants they attack emit it into the environment. PubChem also notes it among food ingredients, citing the FooDB database. In our set of 85 cultivars, farnesene appears in the profile of eleven of them.

How long does farnesene take to reach the body and how long does it stay?

Unknown. Neither of the two studies on farnesene measured its concentration in the blood of either humans or animals, so the absorption time cannot be provided. Our boiling point file does not even have such a number for this compound: a query to PubChem ends with a 404 response.

This file lists eleven compounds, and two of them have no entry, namely farnesene and bisabolol. Six have values measured at atmospheric pressure. Humulene has the only reading taken at a pressure of 3 mm Hg, which is in conditions close to vacuum, where the same substance boils hundreds of degrees lower than in an open vessel exposed to air. Comparing such a reading with the others would be a mathematical error, not a minor inaccuracy.

We do not provide device settings, and this is not editorial caution, but a lack of basis: such a number does not result from this data. The boiling point describes a pure reagent heated in a vessel, not resin spread on flowers in a vaporizer chamber. We break this down separately in the text about vaporizing terpenes.

The route of administration determines the course more than the strain itself. After vaporization, the substance passes from the lungs to the blood almost immediately, so the first sensations appear after a few minutes, intensity increases for another ten to thirty minutes, and the whole effect lasts for two to four hours. After ingestion, the material first passes through the intestine and liver, so the first sensations are waited for from half an hour to two, and the episode lasts six, sometimes eight hours. This is where the most common mistake in oral administration comes from: those who think nothing is happening after thirty minutes and take another dose will receive both doses at once. The above ranges describe the route of administration, not this strain; pharmacokinetic studies for a single cultivar have not been published.

What have studies shown about the effects of farnesene?

Nothing about effects in mammals. The evidence base for this project has two entries for farnesene: an experiment on a plant inhabited by aphids and a review of insect literature. The first yielded a negative result, and the second does not deal with mammalian organisms at all. There is no third entry for this compound in the database.

Let’s compare this with the entirety of the database. It consists of 22 entries spread over eleven terpenes, and not one of them includes humans. Two are outside mammalian biology, and both belong to farnesene. No other compound from this set has a file composed solely of works on plants and insects. This is not a criticism of the authors: both works answer questions of entomology and do so reliably. The point is that the question of the impact on patients was not raised in either of them.

What has not been shown about farnesene?

Farnesene has no studies on humans or mammals. The literature on this compound concerns aphids, their alarm pheromone, and plant defense, not pharmacology. No therapeutic effect attributed to it comes from studies on mammalian organisms. This is the record from the database of this project and it speaks to the state of the literature, not to the safety of use.

Let’s break this down. The 2010 experiment did not concern mammals at all, and even in the insect, it did not confirm what it was looking for: the rocket plant continuously emitting this compound did not deter aphids from settling. A negative result in an entomological study says nothing about humans, but it does say a lot about how cautiously one should read statements about the alleged defensive role of this molecule.

To say anything about the effect of farnesene on a patient, three things would need to be present, which are not: the quantification of the compound in a specific batch of herb, measurement of how much of it passes into the blood after heating, and observation with a defined endpoint described in humans. All three are missing at once, not just one of them.

There is also a limitation that popular strain descriptions are silent about. Profile databases list only the name without the isomer, so even if a study on (E)-beta-farnesene in rodents were published tomorrow, it would not be known whether it pertains to what was indicated in the flowers. Thus, the statement about the lack of studies on mammals is the first of two limitations, not the only one.

In comparison: the other ten terpenes in this set have at least one study on rodents or in cell culture in the database. Farnesene is the only one for which there is neither.

So a fair answer is: there is nothing to summarize, and we do not fill the gap with a general statement about the role of terpenes, because a statement about a group of compounds does not become data about one of them.

What adverse effects have been reported after farnesene?

None. There is not a single report in the database of this project for this compound, as both entries concern aphids and rocket, not individuals taking the drug. The lack of reports is not evidence of safety here, but a result of the fact that no such observation has been conducted.

The statement that terpenes at high concentrations can be irritating to the respiratory tract and skin describes an entire group of volatile compounds and does not come from a measurement made for farnesene. Transferring it to a single name from the composition would be exactly the error that the previous section warns against. We do not know the quantity: none of our databases provide how much of this compound remains in the vapor after heating the flowers, nor how much was present before heating.

Reports of adverse effects are collected for a medicinal product with a batch number, not for a strain name, so the following pertains to cannabis herb as a group of raw materials. The most commonly reported effects are dry mouth, red eyes, and increased heart rate. Less frequently described are dizziness upon rapid standing, daytime drowsiness, and temporary worsening of short-term memory, as well as anxiety increasing with dosage. A separate issue is medications taken concurrently, especially sedatives and those affecting coagulation: their assessment requires knowledge of the entire list of preparations, not just the description of the plant. We do not provide the frequency of these symptoms numerically, as public compilations for cannabis herb in Poland do not separate them by individual products.

Which strains from Polish pharmacies have farnesene as the leading terpene?

None. The pharmacy list, on which our inventory of 141 entries stands, recognizes only six terpene names: myrcene, caryophyllene, limonene, terpinolene, pinene, and nerolidol. Farnesene is not among them, so it could not be indicated as leading for any entry. In profile databases, this compound appears in the composition of eleven strains.

The distinction between these two lists is substantive, not formal. The pharmacy list assigns one leading terpene to each entry and draws from a dictionary of six names. Profile databases list the entire composition and have a broader dictionary. A strain can thus have farnesene in its profile, while the pharmacy list records limonene or myrcene. This is the case with Mac 1 and GMO: the share table on budcare.pl places farnesene first, while the pharmacy list indicates limonene and myrcene for these entries.

The following table lists all eleven strains, with each producer from the list and the terpene that the list recognized as leading. The last column indicates whether the profile description is confirmed by one source or two differing from each other.

These entries are produced by six manufacturers: Cantourage, Four 20 Pharma, S-LAB, Suprobion, Synoptis Pharma, and Canopy Growth. The availability of individual entries changes from month to month, as it depends on what a given manufacturer has released for sale, and the current state is maintained by the list of available strains. The positions mentioned here are raw materials dispensed by prescription, not store inventory; the store collects a separate category of herb.

How do profile databases differ in describing farnesene?

In scale and consistency. The budcare.pl service lists farnesene in the composition of fourteen out of one hundred forty-six entries, while medweed.pl lists it in two out of sixty-five. Additionally, both lists within one service can diverge: for two strains, the composition list includes farnesene, while the share table from the same site omits it.

These two strains are Purple Octane and Northern Berry. In both cases, the composition list opens with farnesene, while in the share table, its place is taken by bisabolol, which is not present in the composition list. The divergence also goes the other way: for two other entries, marked as Facade and Big Purple Dragon, farnesene appears in the share table, although the composition list omits it.

The combined profile, which is created from both sources, assesses compliance separately for each strain. Of the eleven strains with farnesene, both services describe only two simultaneously, namely Mystic Wonder and Northern Berry, and for both, the composition does not match. For the remaining nine, farnesene comes from one service, as the other either does not describe that entry or provides a shorter composition.

For the reader, this results in one thing. The presence of farnesene in the strain description is information about what the service has written, not a result of quantification assigned to a batch of raw material. Two services looking at the same product can provide two different compositions, and they did so for both strains they describe simultaneously.

Why do we not provide farnesene share in numbers?

Because we do not know the denominator. In those entries of the budcare.pl service where farnesene has an assigned number, the sums of all shares from one entry range from 73 to 125. A value above one hundred cannot be a share of the whole, so the number next to the compound name would suggest a measurement that no one has performed.

The distribution of these sums looks like this: fourteen entries with a number next to this compound yield ten different results, three hit exactly one hundred, and two go higher. The lowest sum is 73, the highest is 125. If the components were given as weight shares of the entire oil, none of these sums could exceed one hundred, as the whole is never smaller than its parts.

Numbers from such a table are also not comparable between strains. For Ultra Jack, the sum is exactly one hundred, and all listed components received equal shares, which looks more like editorial rounding than a result of quantification. For Pave S1, the sum exceeds one hundred by one quarter. Providing a value in the text taken from such a table would be promising the reader precision that is not present in the source.

We therefore provide the composition as composition: names of compounds that the source mentioned, without numbers. This is less flashy than a table with percentages, but corresponds to what can actually be read from this data.

Frequently asked questions

Does farnesene have a calming or pain-relieving effect?

Unknown. There is not a single study with a mammalian model in the evidence base for this project, so no effect in humans can be confirmed or excluded on this basis.

Does any strain from Polish pharmacies have farnesene indicated as the leading terpene?

No. The pharmacy list, on which our inventory stands, recognizes six names of terpenes, and farnesene is not among them. Eleven strains, however, have it listed in their composition in profile databases.

At what temperature does farnesene evaporate?

We do not provide this number because we do not have it. A query about the boiling point of this compound ends with a 404 response in PubChem, and the boiling point of a pure reagent is not a device setting anyway.

Is farnesene from the flowers the same compound as the alarm pheromone of aphids?

Our data cannot resolve this. Entomological works concern the (E)-beta form, while profile databases list only the name without the isomer.

How many strains from this set have farnesene in their profile?

Eleven out of eighty-five. For nine of them, the compound comes from one service, while for two, namely Mystic Wonder and Northern Berry, the sources provide differing compositions.

Why do you not provide farnesene share in numbers?

Because the sums of all shares provided for one entry range from 73 to 125, and a collection in which parts exceed the whole does not yield a number suitable for citation.
