Is there really a difference between Indica and Sativa?
Sativa and indica are two names known to all consumers and are supposed to represent two opposite effects of physical and mental effects for those who use them. But are there really two main types of cannabis as consumers claim, or is it a myth, as the researchers claim?
With the increase in cannabis use for medical purposes in recent years, it is now more necessary than ever to clearly distinguish different types of cannabis from the medical effects expected.
Although it is sometimes botanically possible to distinguish between indica (low-leafed broadleaf plant) and sativa (tall, thin-leafed plant), there is no evidence of difference in effect on sensation after smoking a flower of an indica or sativa plant. It is here that the definition of "strain" or
« variety "Compared to" species "(specie)" type "or" appearance ".
Technically, the word "Strain" is incorrect in English in the botanist context but it is common in the world of cannabis. The correct concepts for describing differences within a particular species are Phenotype, Variety or Subspecies.
Indica Vs Sativa - Which varieties are best suited for health?
There are two main varieties of cannabis plant and each offers a different set of benefits. It is important to understand the difference between the two to find the right strain for each patient.
Each strain has its own range of effects on the body and mind, giving rise to a wide range of medicinal benefits. Indica strains usually provide a feeling of deep body relaxation. Sativa strains tend to provide a more energizing experience.
According to the classification accepted by cannabis producers and consumers, the differences between Indica and Sativa are the psychic or physical impact and the atmosphere that accompanies it. When so-called "Indica" varieties are known to bring a sensation of physical relaxation, in contrast the varieties of "Sativa" type bring a feeling of psychic motivation. Regarding their structure, the plant Indica and in general quite low in size but more compact however Sativa varieties are mostly high in size but quite fine.
Indica and Sativa: Origin, evolution and hypothesis
The words "indica" and "sativa" were introduced in the 18th century to describe different cannabis species: Cannabis sativa and Cannabis indica. The term sativa, named by Carl Linneaus, described hemp plants found in Europe and Western Eurasia, where it was grown for fiber and seeds. Cannabis indica, nominated by the naturalist Jean-Baptiste Lamarck, describes the psychoactive varieties discovered in India, where it was harvested for its seeds, fibers and hashish production.
Lamarck's definition was accepted, but with the beginning of medical research on cannabis in the West in the nineteenth century, researchers questioned him: the famous Irish doctor William O'Shaughnessy used the term cannabis indica to describe cannabis psychoactive and cannabis sativa to describe cannabis. In 19, he wrote: "There are many different points of view about whether cannabis in Europe is different from that of Asia and India. The unusual symptoms it causes in its users are the result of increased secretion of resin, virtually nonexistent in European cannabis. Both plants are completely identical and even identical in all physical characteristics, and I do not think they are different except for the climate in which they grew. "
Characteristics of differences between Indica and Sativa
Indica and Sativa are the two main varieties of the cannabis plant. There are also so-called "hybrid" varieties that generally contain 50% Indica and 50% sativa, such as the Amnesia variety.
Indica varieties are better suited to indoor growing as they take up less volume. Sativa varieties are better suited to growing marijuana outdoors because of their size (they can reach a height of several meters).
The classification of the Sativa and Indica categories according to the botanical characteristics is based on the morphological differences (in the structure of the plant): the indica plants have a lower height, their leaves are wider, while the sativa plants are higher with long, thinner leaves.
It is very important to point out that recent studies in this area have not shown any correlation between these two classification methods. For example, cannabis, which, according to all botanical characteristics, corresponds to the Indica definition, will not necessarily have any psychoactive effects associated with Indica.
Indica plants ripen faster than Sativa plants and both species also have different odors due to different trapezoidal content.
Sativa or Indica: It's all about appearance
Believe it or not, those who have seen a lot of weed in their lives can identify different strains of cannabis simply by their appearance. With hybrids, this can sometimes be complex, but with the indica and pure sativa varieties, there are really quite distinct differences in appearance.
The Psychotropic Effects of Different Strains of Cannabis
Indica varieties bring a physical effect expressed by a pleasant sensation of physical relaxation but also psychic.
On the other hand the use of Sativa varieties is more psychic, they bring a feeling of motivation and well-being.
Both species have a different medical effect, you can adjust and adjust the percentages of each variety type to create a balance that meets specific requirements.
The main qualities of Indica medicinal strains include:
- Increased mental relaxation
- muscle relaxation
- reduces nausea
- decreases acute pain
- increases appetite
- increases dopamine (a neurotransmitter that helps control the reward and pleasure centers of the brain)
- for night use
The main qualities of Sativa medicinal strains include:
- treats chronic pain
- increases concentration and creativity
- increases serotonin (a neurotransmitter involved in the regulation of learning, mood, sleep, anxiety and appetite)
- for day use
The distribution between "sativa" and "indica" is not exact
The cannabis-tolerated classification that distinguishes Indica and Sativa is inaccurate and does not necessarily describe the fundamental difference between the different varieties of hemp, including cannabis.
Genetic research conducted by Canadian universities in collaboration with "British Columbia" and "Dalhousie" has been published by PLoS ONE Magazine.
"We need a new classification system to provide the consumer with reliability and accuracy," says the chief scientist of the research team.
What does the research say?
The study concludes that the display of the results compromises the classification system existing in the global cannabis market, in particular the differentiation between Sativa and Indica, and presents scientists with a new picture of the genetic differences between the different strains of cannabis.
The two scientists who led the research team are Jonathan Page Senior Botanist at British Columbia University and Shane Miles Researcher in Genetics at Dalhousie University in Canada.
The study carried out is considered the most important to date in the field of cannabis. In an interview with a Vancouver Sun reporter, Jonathan said, "The main reason for this study is the lack of scientific data on the subject of cannabis," according to him, because of the illegal status of the plant.
During the study 81 samples of cannabis and 43 samples of other hemp, were analyzed, the goal being to look for links between the different varieties. Because indeed cannabis is a variety of hemp, it is the Indian hemp, the one that contains the molecule THC9.
Indica vs. Sativa: Effects
For further explanation we must add that THC (tetra-hydro-cannabinol), the most famous cannabinoids is mainly responsible for euphoria. CBD (cannabidiol), the second most famous cannabinoid, has no psychotropic effects but has exceptional medical aspects. In addition, there are a number of prominent cannabinoids (CBN, THCA, CBDA, THCV, etc.) as well as dozens of other cannabinoids that have not yet been fully studied.
Today, researchers working to develop new strains of cannabis generally work on varieties containing a higher percentage of CBD than THC in order to exploit the medical benefits of the molecule present in the plant.
The study is based on the assumption of currently recognized species and on the classification of genetic evidence. Thus, with most of the samples tested, the researchers determined that in most cases there is no compatibility between the genetic characteristics on the seed package offered by the companies of different cultures, and the results of the tests. tests carried out.
At the end of the test, it was discovered that 5 samples on 82 met the criteria reported by the producers.
Classification of different strains and varieties
In conclusion, some of the samples that were described as "100% Sativa" are infused with "Indica" origin. The researchers also found that some of the "Indica" variety samples, mostly from Afghanistan, are genetically more similar to industrial hemp than cannabis (Indian hemp).
"Cannabis growers report the percentage of Sativa or Indica on all species but they are not precise at all," say researchers
John Paige concludes with: "At this time, the genetic identity of cannabis plants on the market can not be determined with precision, and we need a new classification system, proposed by a reliable and accurate classification . "
We can say that today it is still difficult to obtain a classification and to be able to affirm that it is an Indica or Sativa variety. It is therefore necessary to learn about a variety before declaring its origin Indica or Sativa.
Advances in cannabis research are such that we can expect a clearer and more accurate classification in the near future. Waiting for you to judge what benefits your plant brings you ...
