King Sherb (Cannabis flos S-LAB): lineage OG Kush Breath and caryophyllene in the lead
King Sherb is a hybrid from S-LAB with lineage OG Kush Breath and Blue Sherbet, described in Polish databases by a single source. We collect here the profile composition, the state of evidence for caryophyllene, and what has not been checked for this cultivar.

- Who supplies. Exclusively S-LAB, so there is nothing to compare versions with, and a supply break means no availability of this strain, not another version of it.
- Profile. Caryophyllene leads, alongside limonene, myrcene, and nerolidol. We do not provide percentage shares because sources count them against different wholes.
- Origin. The lineage is established, with parents being Og Kush Breath and Blue Sherbet.
- What is missing. The profile describes one source, so there is nothing to compare it with.
What is this strain and where does it come from?
King Sherb is a hybrid with indica dominance, created by crossing OG Kush Breath with Blue Sherbet. This lineage is provided by a seed database attributing the strain to the breeder In House Genetics, and it is confirmed by the Polish description of the S-LAB raw material premiere. In pharmacies, the strain is available as cannabis flower dispensed by prescription.
The lineage is a value in itself here, as in this comparison of strains, twenty-five cultivars out of eighty-five do not have established parents. King Sherb belongs to the better-documented part. We found the lineage record in two independent places: in a database organizing the genealogies of seed strains and in a Polish announcement about the introduction of S-LAB flower into circulation. Both indicate the same parental pair, so it is not a reading from one entry copied further.
The Sherb part in the trade name corresponds to the second parent, but the mere coincidence of words does not resolve anything. In this same comparison, ten strains have the word kush in their name, and half of them do not have documented origins, so a common term can be a mere sales tactic. The genetics of King Sherb is described by the database as a hybrid with indica dominance, and this description comes from one source, not an averaged result of several independent designations.
Which producers supply this strain to Polish pharmacies?
One. King Sherb is supplied to Polish pharmacies exclusively by S-LAB, and in the list of raw materials, it corresponds to a single trade position. Therefore, there are no competitive versions to choose from, and the differences that a patient sees arise from the production series, not from a choice of producer.
| Producer | Registered name without numerical part | Declared THC content | Genetic description in source |
|---|---|---|---|
| S-LAB | Cannabis flos S-LAB | 19.8-24.2% | hybrid with indica dominance |
The registered name in pharmacy circulation contains the number of declared potency. We provide it without this part because the value on the label is subject to a manufacturer tolerance of up to ten percent in either direction, and a single number written in the text pretends to an accuracy that does not exist. The same declaration broken down accurately gives a range of 19.8-24.2%.
Differences that are not visible in such a table must be sought in the series documentation. Each batch of flower has its own certificate of analysis and its own measurement result, so two packages of the same name can lie at opposite ends of the allowed range. With plant material, this is a normal state of affairs, not a manufacturer defect.
The presence of the strain in pharmacies changes at a rhythm that the pharmacy cannot influence. The raw material goes through successive series releases, the importer may depend on a single delivery, and the permit for admission has its expiration date. The database from which the description of the King Sherb profile comes currently marks this position as unavailable. The current state of pharmacy stocks is maintained exclusively in the list of strains currently available in Polish pharmacies, and other positions from the same producer are collected in a study of the portfolio S-LAB. Outside of pharmacy circulation stands the retail category of cannabis flower available without a prescription, which is a separate type of product and not a substitute for pharmacy raw material.
What does this strain smell and taste like?
- caryophyllene caryophyllene (leading in the pharmacy list)
- limonene limonene
- myrcene myrcene
- nerolidol nerolidol
Citrusy and peppery. The Polish database describing this raw material lists four scent impressions: citrus, peppery, spicy, and earthy. The set fits the profile composition, where alongside caryophyllene stand limonene, myrcene, and nerolidol, although the aroma description remains a sensory impression, not a result of laboratory measurement.
The profile composition is provided as a composition, without shares. The reason is prosaic: databases do not say what these shares refer to, and when attempting to sum them, numbers come out that do not add up to a whole. For some positions, the sum stops below half, for others it reaches four-fifths, so the denominator is different each time. The order in such a set thus carries one piece of information: caryophyllene has come to the forefront.
The description of the smell and the description of the composition are two different registers. The citrus impression can easily be linked to limonene, and the peppery note to caryophyllene, but the nose does not measure concentrations, and the same note can come from a compound that is not in the set at all. Therefore, taste notes remain a commercial description, not analytical data. Separate studies collect what has been shown for limonene, for myrcene, and for nerolidol.
The pharmacy flower reaches the patient in a sealed package, and grinding usually releases a more pronounced smell than whole flowers. The intensity can also be a derivative of the age of the series, as volatile components diminish during storage, even at the correct temperature.
How long does it take for the strain to take effect and how long does the effect last?
This depends on the route of administration, not the strain name. For King Sherb, no one has measured the course separately, so the only thing that can be honestly provided are the ranges described for cannabis flower taken by inhalation and orally. The following paragraph collects them in a form that we use throughout this comparison.
The route of administration determines the course more than the strain itself, and the ranges below describe just that, not this cultivar, as pharmacokinetic studies for a single cultivar have not been published.
| Vaporization | After swallowing | |
|---|---|---|
| First sensations | after a few minutes | from half an hour to two |
| Onset | another dozen to thirty minutes | slow, over several hours |
| Total duration | within two to four hours | after six, sometimes eight hours |
| Typical error | none | taking a dose after thirty minutes, which gives both doses at once |
For King Sherb itself, this does not change anything in either direction. The composition led by caryophyllene does not have its own assigned course over time, as such measurement requires blood assays, not a description of the strain. The difference that a patient notices between two trade names usually comes from the measured portion of material and the setting of the equipment, not from genetics.
What is known and what is not known about the effects of this strain?
Nothing is known about the strain itself. No study has tested King Sherb as a preparation or compared it with another flower. Available evidence concerns a single component of the profile, caryophyllene, and comes from studies on animals and receptor binding measurements in vitro.
| Study | Model and route of administration | What was shown |
|---|---|---|
| Gertsch J et al., 2008 Proceedings of the National Academy of Sciences (PNAS) PMID:18574142 |
mouse (in vivo) and test tube (receptor binding, human cells) | (E)-caryophyllene selectively bound to the CB2 receptor (Ki = 155 nM) and inhibited carrageenan-induced paw swelling in wild-type mice, but not in CB2 receptor knockout mice (Cnr2-/-), indicating a CB2-dependent mechanism; the study did not include any anxiety tests. |
| Klauke AL et al., 2014 European Neuropsychopharmacology PMID:24210682 |
rodent (mouse) | Oral caryophyllene reduced late inflammatory pain in mice in the formalin test in a CB2 receptor-dependent manner, with no effect on the early phase; in a neuropathic pain model, it alleviated thermal hyperalgesia and mechanical allodynia without developing tolerance with chronic administration. |
The boundary of these results is as important as the results themselves. In neither of the two studies was caryophyllene tested on humans or in inhaled form from flower; both works concern oral or systemic administration in mice in pain and inflammation models, not sleep or mood.
The producer’s material and patient reports create a separate record. The database describing this raw material assigns it relaxing and balanced effects, but this is a record of expectation, not a measurement result. The entirety of evidence for caryophyllene itself, apart from trade names, is collected in a separate study.
What side effects have been reported from this strain?
None, if the question concerns only this name. There is no public compilation of symptoms attributed to King Sherb, as the Polish drug safety supervision does not maintain statistics divided by cultivars. What can be reliably described concerns cannabis flower as a whole group of raw materials dispensed from pharmacies.
Reports of side effects are collected for medicinal products with a batch number, not for the strain name, so the following concerns cannabis flower as a group of raw materials. The most commonly reported 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 a description of the plant. We do not provide the frequency of these symptoms numerically, as public compilations for cannabis flower in Poland do not separate them by individual products.
If such statistics were to be created for King Sherb, it would have to start from the batch numbers introduced by S-LAB and from reports linked to a specific package. With a single trade position and variable availability in circulation, the collected material would be so sparse that it would not be possible to calculate frequencies. This is a limitation of the data collection method, not an indication of anything regarding the safety of the strain itself.
How to vaporize this strain?
Just like any other pharmacy flower, because the vaporizer setting is adjusted to the profile composition, not the trade name. Caryophyllene, which comes to the forefront in this profile, has a boiling point significantly higher than lighter components, so no single setting will extract everything at once.
| Profile component | Boiling point at atmospheric pressure |
|---|---|
| myrcene | about 167 °C |
| limonene | about 178 °C |
| caryophyllene | about 257 °C |
| nerolidol | 275-277 °C |
The numbers in the table come from chemical sheets of pure compounds, not from measurements in the vaporizer chamber, and that is their boundary. The temperature on the display describes the heater or airflow, not the interior of the material, which can be several dozen degrees cooler. A separate study explains why published temperature sets can contradict each other.
In practice, this means that lower settings primarily release the most volatile components, while heavier ones remain in the material for higher settings. With a profile led by caryophyllene, the difference between the first and last draw can therefore be quite pronounced in taste. Vaporizer manufacturers provide their own recommendations for their devices, and it is those, not the boiling tables of pure compounds, that describe specific equipment.
The range visible in the table also explains why one range of settings describes this profile worse than two. Between the lightest and heaviest of the listed components lies over a hundred degrees, so material given at a low setting retains some content for a higher setting. This results from the boiling points themselves, not from properties assigned to King Sherb, and it applies equally to any flower with a similarly stretched composition.
Which strains are related to it?
| Strain | Common parent | Leading terpene | Producers |
|---|---|---|---|
| Original Gangster Deluxe | Og Kush Breath | terpinolene | Canopy Growth |
One, and that from one parent. In this comparison of strains, Original Gangster Deluxe is related to King Sherb, as both lines carry OG Kush Breath in their lineage. The second parent is different in both cases, so we are talking about half-siblings, not identical twins.
Original Gangster Deluxe reaches Polish pharmacies from a different producer than King Sherb and has a differently arranged profile: it leads with terpinolene, not caryophyllene. This well illustrates that a common parent does not directly translate into a common smell or common composition. The description of that strain is conducted separately.
The list of relationships in this comparison is created solely from documented lineages and deliberately omits parents that are broad families of style. If one were to consider as siblings every strain that has somewhere in its tree a line of OG Kush or Afghan, a graph would emerge in which almost everything connects with everything and thus says nothing.
A separate note concerns the second parent. Blue Sherbet does not have its own position in Polish pharmacies, so this branch of the lineage does not generate any additional relationships here. A complete list of cultivars currently in circulation is collected in the overview of available medical marijuana strains.
Frequently asked questions
Is King Sherb available without a prescription?
No. Cannabis flower is a pharmaceutical raw material dispensed by a doctor’s prescription in the Rpw category, so the pharmacy dispenses it only on a prescription issued by an authorized physician.
What is the THC content of this strain?
The source provides a declared value with a manufacturer tolerance of up to ten percent, which gives a range of 19.8-24.2%. We do not provide a single number, as the label applies with a deviation in both directions.
Who produces King Sherb for Polish pharmacies?
S-LAB. In the list of raw materials, the strain corresponds to one position of this producer, so there are no alternative versions or choices between producers.
Which component leads in the profile of this strain?
Caryophyllene. The composition description comes from one source and lists alongside it limonene, myrcene, and nerolidol, without providing shares in the profile.
Does King Sherb help with sleep?
It is not known. No clinical study has been published for this cultivar, and studies on caryophyllene were conducted on mice and in pain models, not sleep.
Is the strain consistently available in pharmacies?
No. Availability depends on the release of subsequent series and the importer’s decisions, and the database describing this raw material currently marks it as unavailable.
