Kratom is a naturally occurring, evergreen tree that grows best in rich soil in hot and humid environments that do not have cold winters. It belongs to the Rubiaceae family of flowering plants and its botanical name is Mitragyna speciosa and is cultivated in Thailand, Malaysia, Indonesia, Papua New Guinea, Bali, Vietnam, and Borneo.
The attention this plant has stirred comes from its leaves. They are said to possess opiate- and cocaine-like effects. Consumption in low doses results in energizing (stimulant) effects whereas consumption in high doses results in pain-relieving (analgesic) and sleep-inducing (sedative) effects. Kratom, however, is not an opiate. It does, however, work on the same receptors as opioids.
Other Names Kratom Goes By

Origins
Kratom is indigenous to Southeast Asia, the Philippines, and New Guinea. Thailand is considered its original home. It has been used for centuries for medicinal, therapeutic, recreational, and religious purposes.
Historical records show that northern Malaysians and southern Thai laborers like fisherman, farmers, and rubber-tappers used it much like coffee is used today. They either chewed, smoked or made tea with fresh or dried leaves to fight fatigue and increase productivity.
In Thailand, it was also used in socio-religious ceremonies and to treat various medical conditions, such as morphine dependence. In rural areas, it was used to self-treat medical issues like diabetes, diarrhea, fever, and pain and used it as a wound poultice
When opium and heroin become scarce in Malaysia, it was used as a substitute. Ancient Buddhists were also known to have used it as a healing tool and a meditation tool.
The first Western descriptive record of Kratom is attributed to a Dutch botanist named Pieter Willem Korthals. Korthals was the official botanist for the Dutch East India Service, a trade and shipping company, between 1831 and 1836. It is said he assigned the plant to the Mitragyna genus because the leaves and the stigmas of the flowers resembled the shape of a bishop’s mitre. In 1895, a British surgeon known as George Darby Haviland confirmed Korthals description.
Also in that year, Edward Morell Holmes, a British botanist, lecturer, and curator of the Materia Medica Museum of the Pharmaceutical Society 1872-1922 noted its use as an opium substitute. Two years later in 1897, Henry Nicholas Ridley, an English botanist, geologist and naturalist documented that Kratom’s ability to act as a substitute for opium could be used to help people find relief from opium addiction.
How Kratom Works on the Body
The phytochemicals (active compounds found in plants) found in Kratom are designed to interact with opioid receptors that are part of the opioid system that controls pain, reward, and addictive behaviors.
There are three classes of opioid receptors – μ, δ, and κ (mu, delta, and kappa) and results show that mitragynine and 7-hydroxymitragynine, the two main alkaloids in Kratom, are partial agonists at the human mu-opioid receptor and competitive antagonists at the kappa and delta opioid receptors. When the alkaloids bind with the opioid receptors they release neurotransmitters that create the dose-dependent effects Kratom is known for.
At low doses, the alkaloids of Kratom strains bind to the Kappa opioid receptors and the neurotransmitters produce stimulating effects and in high doses, they tend to attach to MU receptors and the neurotransmitters produce analgesic effects.
Benefits of Using Kratom
The large number of active compounds and the variety of available strains have contributed Kratom’s versatility as a herbal supplement.
1. Kratom as an Analgesic (pain relief)
Ethnobotanist, pharmacognosist, and author Daniel J. Siebert once described Kratom as one of the most effective herbal analgesics, second only to opium.
The two main alkaloids responsible for the analgesic properties of Kratom are mitragynine and 7-hydroxymitragynine. They activate the same opiate receptors that control pain, reward, and addictive behaviors as prescribed opiate medications do. They reduce pain perception and the intensity of pain signals reaching the brain and influence the regions of the brain involved in regulating emotion subsequently lessening the effects of painful stimuli. The presence of other alkaloids like Corynanthiedine (an opiate antagonist) safeguards users from the side effects associated with opiate use.
Users report using Kratom for pain relief that is the result of headaches or migraines, Multiple Sclerosis, Rheumatoid Arthritis, Irritable Bowel Syndrome, Osteoarthritis, damaged Muscles, Scoliosis, Neck Soreness or Strain as well as for injuries like broken bones, scrapes, and burns.
Dosing for pain relief is moderate to high depending on the severity of pain and the following strains in the red vein variety have been shown to be most effective.
- Indo
- Borneo
- Bali
- Maeng Da
2. Kratom for Opiate Withdrawal
Historically in South East Asia, Kratom was used to wean addicts off heroin. For many users, the inability to cope with opiate linked withdrawal systems is what drives them back to using. Users say that using Kratom helps to ease opiate withdrawal symptoms like restless legs, diarrhea, bone and body aches, fatigue, and irritability.
Also, as alkaloids found in Kratom are partial agonists unlike opiates that are full agonists, they create less intense interactions and may be used to ease opiate dependence.
Dosing for opiate withdrawal is moderate to high depending on the severity of pain and the following strains in the red vein variety have been shown to be most effective.
- Indo
- Maeng Da
- Bali
- Borneo
The use of Kratom for opiate withdrawal is not without controversy though. Proponents for its use in this regard point to the numerous success cases while detractors point to its addictive properties that may result in dependency.
3. Kratom for Energy and Focus
As Kratom belongs to the same plant family as coffee, it’s stimulating effects are not surprising. The alkaloids increase blood flow to the brain and activate adrenergic receptors that boost your energy and enhance motivation, focus, and concentration.
Dosing for energy and focus is low and the following strains in either green or red vein colors have been shown to most effective.
- Thai and Maeng Da – These two strains are best for vigor, focus and memory enhancement.
- Malaysian – This strain is best is used for memory and focus.
- Borneo – The White Vein strain is best used for an energy boost
4. Kratom as an Immune System Booster
Herbal supplements have a long history of being used to boost the immune system enabling it to fight off infections ranging from a cold to more serious conditions like cancer. It can also help to reduce their duration and intensity.
Kratom has been shown to boost the immune system through four main alkaloids collectively known as Immunostimulants. They are – Mitraphylline, Isopteropodine, Isorhynchophylline, and Isomitraphylline. It also has anti-viral and anti-bacterial effects and is a potent anti-oxidant helping the body flush out toxins, vital in preventing significant illnesses such as colon cancer.
It can also restore insulin production for individuals who have type 2 diabetes, regulate blood pressure for hypertensive individuals, and its anti-mutagenic component reduces the risk of cancer
Dosing for immune system support is low to moderate and the following strains in the green vein variety are most effective.
- Borneo
- Malaysian
5. Kratom as a Nootropic
Nootropics are compounds or supplements like Ginkgo Biloba and Ginseng that are known to improve cognitive function.
As a nootropic, Kratom boosts concentration and memory recall, improves in mood and motivation an helps you manage stress. Its antioxidant properties offer protection against neurodegenerative conditions
Dosing for nootropic effects is low to moderate to create more stimulating than sedating effects and the following strains in either the green or red vein variety are the most effective.
- Thai
- Maeng Da
- Malaysian
6. Kratom for Euphoria
Some of the alkaloids found in Kratom are known to bind to the opioid receptors and stimulate the sympathetic nervous system, which in turn sends a signal to release endorphins. Endorphins are hormones that once triggered reduce your perception of pain and also trigger a positive feeling in the body described as euphoria.
Endorphins are hormones that once triggered reduce your perception of pain and also trigger a positive feeling in the body described as euphoria.
Users of Kratom in a euphoric state are highly stimulated and have a calm state of mind. They are able to focus better and concentrate on complex tasks. They also feel a boost to stamina and endurance.
Dosing plays an important role in getting the desired euphoric effect.
- 1 gram – 3 grams produces both energetic and euphoric effect.
- 4 grams – 6 grams produces strong euphoric effect.
- 7 grams – 10 grams produces more sedating effects and less euphoric effect.
The strains that are most effective at producing euphoric effects are the following in either the green or white vein variety.
- White Borneo
- Maeng Da
- Malay
How is Kratom Consumed
Options for consuming Kratom include powders, capsules, extracts or tinctures. Choice is usually based on personal preference stemming from factors like ease of use and convenience.
Kratom Powder
Kratom powder is made from dried pulverized leaves. The powder can then be consumed as is and the toss and wash method is the most common way to do so. This involves scooping a spoonful of kratom powder into your mouth and then drinking a glass of water to wash it down.
For many, the powder has a bitter earthy taste so it can also be mixed with things like chocolate milk, orange juice, pomegranate juice or coffee to make it taste better. Dosing Kratom power on an empty stomach is recommended for effects to be felt sooner.
Kratom Capsules
Kratom capsules are either veggie or gelatin capsules that contain Kratom powder. Veggie capsules are pricey and are made of hypromellose, cellulose, and purified water. They are gluten-free, vegan, non-GMO, and free of any preservatives and chemicals and dissolve quicker than gelatin capsules. Gelatin capsules, on the other hand, are more affordable than veggie capsules but they are made from animal by-products which and are prone to allergic reactions.
Capsules are popular as they can be consumed discreetly and its easier to keep track of dosage amounts. Effects take longer to be felt though as the body has to dissolve the capsule first before it can get access to the powder.
Capsules come in different sizes based on the amount of powder they contain
- Size ‘000’ – 1 gram of Kratom per capsule
- Size ‘00’ – 0.735 grams of Kratom per capsule
- Size ‘0’ – 0.5 grams of Kratom per capsule
- Size ‘1’ – 0.4 grams of Kratom per capsule
- Size ‘2’ – 0.3 grams of Kratom per capsule
Kratom Tinctures
Kratom tinctures are a liquid form of the herbal supplement made by extracting its active compounds from its leaves using food grade alcohol. Tinctures are potent as they contain a full spectrum of the alkaloids and their effects are felt relatively quickly when consumed via the sublingual method. This involves placing a few drops under your tongue and holding them there for up to 30 seconds.
Tinctures can be pricey and may cause adverse reactions from solvents used to make them finding their into the final product. They must also be stored in amber or blue colored bottles to protect it from being oxidized by light.
Many people also tend to make their own as they hard to come by and relatively straightforward to make.
Kratom Extract
Kratom extract is made by boiling a large number of fresh Kratom leaves or powder until a soft, brown substance called resin is created. To boil the leaves either water is used which results in a water-based extract or a polar and nonpolar solvent is used resulting in what is called resin extract.
Extracts are usually made in different potencies from 5x, 10x, 15x, 20x, 25x and 50x and can be used to brew it into a tea, cook it in recipes, eaten raw, or mix it into a smoothie. They can also be further processed into a powder, tincture, or resin.
Dosage Amounts
There is no official recommended dosage amount for Kratom. One reason for this is that it is yet to be subjected to rigorous testing that is used to establish that value. Establishing the dosage amount is further challenged by the number and varying ratio content of the active compounds in each strain.
In addition to the above, factors like gender, age, and condition being treated influence dosage amounts. Establishing your correct dose will, therefore, involve some trial and error. Two things should be kept in mind as you begin the process. The first is to start with smaller amounts and build up. This will allow the body to adjust to the supplement and it also helps you gauge how effective the dosage is.
The second is to alternate between strains so as not create a tolerance for anyone particular strain. This will require testing out different strains with similar properties.
In general, the following has been noted when it comes to Kratom dosage amounts:
- Low doses (1 gram to 5 grams) produce stimulant-like effects predominate approximately within 10 minutes. Effects last 60 to 90 minutes and include increased energy and alertness, decreased appetite, increased sociability and heightened libido.
- Moderate to high doses (5 grams t0 15 grams) produce effects that include anxiolytic (anti-anxiety), euphoria, analgesia (pain reduction), drowsiness, cough suppression and reduction in symptoms of opioid withdrawal.
- High doses (16 grams to 25 grams) produce highly sedating effects describe by many as too strong. This amount is not recommended for inexperienced users.

Kratom Strains
Kratom is grouped by strain or what you could call types. The strains are named after the region from which they originated, cultivated or exported from. These strains are further differentiated by vein color which is the color of the vein running down the center of the leaf. There are three vein color classifications – Red, Green, and White.
Strains by Color
Red Vein Kratom
The Red Vein Kratom strain is the best selling and most widely available strain. It has a higher than average amount of 7-Hydroxymitragynine alkaloid making it a very effective painkiller especially, for chronic pain conditions.
This strain also produces the highest calming and sedating effects that beginners may prefer.
Red vein varieties have different effects and properties. Some strains such as Red Thai and Red Vein Borneo have sedative effects while others like Red Sumatra produce elated mood effects.
Green Vein Kratom
The Green Vein strain combines the best of what the Reid Vein and White Vein have to offer. It is sedating effects are less than those of Red Vein strain and its stimulating effects are less than those of the White Vein Strain.
It’s also recommended as a good strain for first time Kratom users and a must have strain to alternate with to reduce dependence and avoid building tolerance. Additionally, thanks to its balanced effects, it is often used to ease social discomforts.
White Vein Kratom
The White Vein strain is known for its stimulating and positive mood-enhancing effects that boost energy, prevent fatigue, and increase focus and concentration especially, for complex activities.
This strain is most often the go-to pick for those looking to replace their caffeine habits with something similar but that does not come with the same side effects like jitters.
Strains by Region
1. Bali Kratom
Bali Kratom is considered to have the most classic opiate-like effects of all the strains and is recommended for first-time users. It gets its name from the Indonesian island of Bali and today can be found growing in Thailand and Malaysia.
It’s the fastest growing strain and the easiest to produce. For a long time, those two factors made it the dominant strain available in the market. An extremely low price point in comparison to other strains and a high potency content make it the most popular strain amongst users.
It has large, dark-colored leaves that bear both analgesic and sedative properties. When taken in low doses it has a euphoric effect and can boost energy levels. In high doses, it gives a more relaxing effect. It can also modify appetite, provide relief from opiate withdrawal and addiction, and act as an anxiolytic.
Once consumed effects can be felt within 15 – 30 minutes. This quick onset, however, results in effects lasting no more than 4 hours. As a result, it’s therefore common to find this strain blended with a more long-lasting strain like Indo kratom.
Bali Kratom is available in Green Vein Bali, Red Vein Bali, and White Vein Bali strains.
- Green Vein Bali – Reduces stress and anxiety and provides pain relief but without sedating effects but is less potent than Red Vein or White Vein strains
- Red Vein Bali – Ideal for pain-relief, though it does also have a strong sedating effect.
- White Vein Bali – Calms without sedating
2. Maeng Da Kratom
Maeng Da Kratom is a specially bred strain and is considered one of the strongest strains of Kratom. Its origin is unclear but has been narrowed down to Thailand and Indonesia. In Thai, Maeng Da is the name given to an edible water beetle called Leothocerus Indicus. When translated from Thai, the name means “Pimp,” so some do refer to this strain as “Pimp Grade.”
This strain has dark colored leaves whose color intensifies when crushed or powdered. It has analgesic properties but is known best for its energizing and stimulating properties that mitigate sedative effects of strains this potent. Its been shown to reduce symptoms of depression, enhance stamina and enthusiasm, improve memory and concentration and prevent fatigue.
Effects are known to last for up to 8 hours and come on in phases. The first effects can be felt with 10 – 15 minutes then a euphoric peak is usually attained after 45 minutes. Sedative effects are usually felt after 2 hours.
Maeng Da Kratom is available in Red Vein Maeng Da, White Vein Maeng Da and Green Vein Maeng Da strains.
- Red Vein Maeng Da – More sedating and euphoric compared to Green Vein and White Vein Maeng Da strains

Things to Consider When Buying Kratom
The growing popularity of Kratom has led to a rise in the number of manufacturers. First-time users may find themselves overwhelmed by all the variety and may struggle to make the best choice for their personal needs. Following is what you should consider when buying Kratom.
1. Know the source of your Kratom
Kratom strains are identified by the region where it’s sourced and by vein color. The region also indicates what type of effects the strain produces To ensure that the strain you purchase will result in the effect you desire you need to make sure that you know where it was sourced from.
2. Know why you are using Kratom
With Kratom, there isn’t one strain suitable for all people or for all conditions. It’s therefore important to know the condition you are aiming to treat or the effect you wish to create before you start shopping. Not only will this save you money but it will also save you time by helping you narrow down which particular strain you should focus on.
3. Buy only from a licensed and reputable seller
Kratom is currently not subject to rigorous regulations. Unscrupulous manufacturers or sellers looking to make quick money tend to take advantage of this and cut corners. Therefore before buying Kratom you must perform your own due diligence to make sure that you only buy from licensed and reputable sellers who offer quality Kratom strains.
4. Buy more than one strain
Alternating between strains is a recommended way to avoid building tolerance and addiction to Kratom when the option to limit use is not possible due to severe symptoms. Therefore if you are planning to use Kratom for an extended period of time, buy more than one strain.
5. Check for Kratom lab testing
Reviewing lab testing reports especially from third party, FDA licensed labs helps you confirm that purity levels of the Kratom as well as the quantity of alkaloids present. These reports should either be available on the company’s website or on request. If none is available find another seller.
Kratom’s Active Constituents
Kratom contains alkaloids, terpenoid saponins, flavonoids, glycosides, and various polyphenols. Alkaloids are the main active ingredients. They are found in varying amounts in the different strains making some better suited to treating particular conditions compared to others.
