Sourdough (Cannabis flos Aurora): a lineage recorded in the name and limonene in the profile

What is Sourdough and where does its name come from?

Sourdough is a cultivar with a lineage of Wedding Cake x Sour Diesel, described as indica and available in Polish pharmacies as a single item. The name literally summarizes this cross: sourdough refers to the sourness from one parent and dough from the other. The lineage comes from the product description by the manufacturer, not from a variety registry.

The record on which this lineage stands reads "Cake x Sour Diesel" and is found in the description of a specific product from Aurora. We interpret the component "Cake" as Wedding Cake, as that is the full name of this parent in the breeding circuit. Therefore, it is information from the producer about their own product, not confirmation from independent breeding documentation. We note this difference because in the same comparison, with twenty-five cultivars out of eighty-five, the origin remains undetermined, and then we write about it directly.

Both components of the lineage appear in the cluster under different names. Wedding Cake is listed as a parent of three other cultivars available in pharmacies, while Sour Diesel is a parent of one. Thus, Sourdough is a point in a denser network of connections, not a variety standing alone, and that is why a list of related names appears further in the text.

The indica designation for this item comes from the same description as the lineage. It is not the result of a chemotype analysis or an official classification, but rather a commercial label assigned to the product by the manufacturer. We provide it because the patient will see it in the search engine, but we do not base conclusions about how the dried flower will act on it.

Which manufacturers supply Sourdough to Polish pharmacies?

One. Aurora introduced this variety as a single pharmacy item, and no other manufacturer has reported dried flower under this name. The registered name is Cannabis flos Aurora, and the numerical component in it is provided separately as a range. In this cluster, the same manufacturer offers ten varieties.

The numerical component in the registered name is the value declared by the manufacturer, and the permissible deviation from it is one-tenth of that value in both directions. For this item, this gives a range of 26.1-31.9% THC content. Quoting just the number from the label would thus be presenting the midpoint as if it were a measurement of a specific package, which it is not.

One manufacturer means one supply chain, and this is where the variability in availability of this name comes from. When the item disappears from the wholesaler, there is no substitute version under the same designation, so the break lasts as long as the next delivery or as long as it takes to change the entry on the prescription. Names maintained concurrently by several manufacturers mitigate such a loss better, as the absence of one item does not remove them from the market. However, there is no rule: in this set, sixty-three varieties out of eighty-five have exactly one supplier.

We do not record the current state of the assortment in this text, as it changes faster than the page about the variety. We maintain it in the list of medical marijuana varieties available in Poland. Osobno we describe the remaining strains from this producer. It is worth remembering that dried flower from retail sales is a different product than the pharmaceutical raw material issued on prescription and does not replace it in any way.

How does Sourdough smell and taste?

Sour and fuel-like, with an earthy and herbal background and a distinct spicy note. This is how one source describes this dried flower, on which we base the entire profile of the variety. The scent aligns with the name: the first impression is sharp and sour, while sweetness remains in the background. This is not a measurement, just a verbal description.

Beneath this description is a set of five terpenes: bisabolol, caryophyllene, limonene, linalool, and myrcene. The weight order provided by the same source places limonene first and caryophyllene second. However, the rest of the record has a flaw that is better stated directly than covered with a nicely looking number.

The shares given for these five items sum to seventy-four, not one hundred. The missing quarter is not described by anyone: it is unclear whether it concerns terpenes omitted from the list or a different counting method. Since the denominator remains unknown, the number placed next to the terpene name would look like a measurement, which it is not. Therefore, we provide just the composition and the order, without numerical values.

Scent associations are also worth reading carefully. Limonene is associated with citrus peels, kariofilen z pieprzem, myrcene with earth and hops, linalol z kwiatem lawendy, bisabolol z rumiankiem. However, these are sensations attributed to pure compounds, not the result of a sensory evaluation of this dried flower, where each of them stands alongside the others.

How long does it take for Sourdough to start working and how long does it last?

Not for this strain, as the measurement concerned routes of administration, not cultivars. Inhalation through a vaporizer produces effects measured in minutes, while an ingested portion requires a much longer wait and lasts longer. This difference outweighs anything that can be attributed to the name on the package, so we start from there.

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

With Sourdough, caution has an additional reason. The range of THC content given for this item, 26.1-31.9%, places it in the upper part of the pharmaceutical assortment, and the higher the declaration reaches, the less forgiving a single inhalation tends to be. However, this does not affect the clock: it shifts the strength of the sensation, not the moment of its onset or the duration of the episode.

What has been shown, and what has not been shown in studies on this profile?

For the strain itself, nothing has been shown, as no one has studied it separately. However, there are studies on limonene, the leading component in this profile, conducted on rodents. These are two different levels of evidence that should not be conflated, so we separate them below instead of combining them into one sentence about effects.

The first study was published in the journal Phytomedicine in 2002 (to Vale TG, Furtado EC, Santos JG, Viana GS, PMID:12587690). Limonene administered intraperitoneally in mice showed muscle relaxant effects (rota-rod test) from a dose of 50 mg/kg and prolonged sleep induced by pentobarbital at a dose of 200 mg/kg (approximately 2.6 times); in the elevated plus maze test, already at a dose of 5 mg/kg, it reduced the number of entries into the open arms, which the authors described as an anxiogenic effect, not anxiolytic.

The second is fresh and comes from Behavioural Pharmacology from 2025 (Fakhri S, Yarmohammadi M, Abbaszadeh F, Kiani A, Farzaei MH, PMID:40622197). Limonene reduced paw swelling induced by carrageenan in rats and pain responses in the formalin test in mice; the effect was associated with the l-arginine/nitric oxide/cGMP/KATP channel pathway and the involvement of opioid and benzodiazepine receptors.

We provide the boundary of this data literally, as it is often omitted. No anxiolytic effect of limonene has been demonstrated in humans. It has also not been shown that isolated limonene has anxiolytic effects in animals; the only available data from the elevated plus maze test showed an opposite effect in mice, reducing the number of entries into the open arms even at a low dose.

Separately stands what is not a study. The product description assigns relaxing effects to this strain, patients describe it in their own words online. Both remain a narrative, not a measurement, and through repetition do not turn into evidence. We discuss limonene more broadly in a separate text.

What side effects have been reported for this strain?

None specifically attributed to it. The reporting system links the description of the event with the medicinal product and the batch number, and the strain name is not a reporting unit in it. Everything that can be honestly written here pertains to hemp flower as a group. This boundary is a property of the data collection system, not a gap in the description.

Reports of adverse effects are collected for medicinal products with a batch number, not for the strain name, so the following pertains to hemp dried flower as a group of raw materials. The most frequently reported symptoms are dry mouth, red eyes, and increased heart rate. Dizziness upon rapid standing, daytime drowsiness, and temporary worsening of short-term memory are less frequently described, as well as anxiety that increases 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 hemp dried flower in Poland do not separate them by individual products.

Additionally, there is a note arising directly from the manufacturer's declaration. An item from the upper range of THC content may be worse tolerated by someone without prior exposure, and the intensity of the mentioned symptoms increases with the dose. The selection of dosage and assessment of whether such potency is even an option belongs to the attending physician, not to the description of the strain.

At what temperature should this dried flower be vaporized?

There is no single correct value for the strain; instead, there is a range of boiling temperatures for its terpenes. Limonene boils at 177.8 degrees, myrcene at 166.8, linalool at 195.5, and caryophyllene only at 257.5. One setting will not vaporize them in the same proportion. The vaporizer provides the temperature of the heating element.

The boiling values come from chemical databases and pertain to the pure compound under atmospheric pressure. Caryophyllene shows why this caveat is not a formality: the same compound was also measured under reduced pressure, resulting in about 130 degrees instead of 257.5. Thus, a comparison of temperatures without specified pressure says less than it seems at first glance. Between the lowest and highest of the values given above lies over ninety degrees of difference, and it is this range, not just the name on the jar, that determines what will make it to the vapor.

For bisabolol, the fifth component of this profile, there are no boiling values in our collection at all. We do not add it by analogy to other sesquiterpene alcohols, as no such measurement has been provided in available databases.

The practical consequence is simple: lower settings primarily extract the citrus and earthy parts from this dried flower, while higher settings add a spicy note and change the character of the vapor. We explain separately, why the vaporizer setting is not the temperature of the dried flower, i why terpene temperature tables can contradict themselves.

Which pharmaceutical strains are related to Sourdough?

Four, all on the Wedding Cake or Sour Diesel side: Chemango Kush, Farm Gas, Wedding Pie, and Wedding Pop Triangle. Each shares exactly one parent with Sourdough, none both, so we have half-siblings here, not a repetition of the same cross under a different name. All four are available in Polish pharmacies.

Three of these names enter the graph through Wedding Cake, one through Sour Diesel. However, a common parent does not promise a similar composition, as the other side of the cross is different each time, and with Chemango Kush, there are as many as four entries in the origin description instead of two.

Kinship should be separated from name similarity, as in this comparison one can be confused with the other. Wedding Pie and Wedding Pop Triangle indeed share a common parent with Sourdough, but the common word itself proves nothing: the component "kush" is carried by cultivars of divergent lineage, and some of them have no established lineage at all. It can also be the other way around. Farm Gas shares a parent with Sourdough without sharing a single word in the name.

We dedicate a separate text to each of these strains: Chemango Kush, Farm Gas, Wedding Pie and Wedding Pop Triangle. Broader families of style, such as "og kush" or "fuel", are not individual cultivars in this graph and therefore do not create siblings.

Frequently asked questions about the Sourdough strain

Can Sourdough be purchased without a prescription?

No. Dried flower is a pharmaceutical raw material dispensed by prescription in the Rpw category, and the strain does not change the dispensing mode.

How many producers supply Sourdough to Polish pharmacies?

One. The strain appears in this listing exclusively as an entry from Aurora, under the registered name Cannabis flos Aurora.

What is the lineage of the Sourdough strain?

Wedding Cake crossed with Sour Diesel. This record comes from the manufacturer's product description, not from an independent breeding registry.

Does limonene have anxiolytic effects?

This has not been demonstrated in humans, and in the available mouse test, isolated limonene had the opposite effect. Research was conducted on rodents and with intraperitoneal administration.

Why do you provide THC content as a range?

Because the value on the label is a declaration from the manufacturer with a tolerance of one-tenth of that value in both directions. For this entry, it gives 26.1-31.9%.

Which pharmaceutical strains are related to Sourdough?

Chemango Kush, Farm Gas, Wedding Pie, and Wedding Pop Triangle. Each shares one parent with it, none share both.
