What is Kratom? Everything you Need to Know

What is Kratom?

Kratom is the dried and ground leaves of the mitragyna speciosa tree, in the same family as the coffee tree.  Native to southeast Asia, kratom has been used traditionally by the locals to alleviate pain and provide energy to get through a grueling days work. (1)

 The effects of kratom are attributed to it's 2 main alkaloids mitragynine and it's main metabolite, 7-hydroxymitragynine which is substantially more potent than mitragynine itself.  The psychoactive effects of kratom can probably be attributed mainly to these two compounds, however there have been over 40 compounds isolated from the plant, many with potential therapeutic benefit. 

In addition to action at the μ-opioid receptor, kratom has been shown to have an effect at the α-2-adrenergic receptor, acting opposite it's chemical cousin yohimbine, and blocking the release of adrenaline. These means that kratom has action at the two receptor sites that are currently used to treat opioid dependence via the drugs methedone and lofexidine.  (3)

What are the Possible Side Effects?

Kratom is purported to have several adverse side effects.

The most obvious and avoidable adverse side effect is dependence.  Dependence and subsequent withdrawal symptoms have been widely reported with continuous use and/or abuse of kratom.

 If you are like me, then you have heard that kratom causes hair loss. For no lack of trying, I didn't come across any evidence of this whatsoever.  Anecdotal reports were inconsistent, with most people (myself included) reporting no noticeable shedding with kratom use.  With this being said, it is not impossible that adding in any sort of chemical compound into your body could cause some hair loss.  Many drugs and other things are known to cause temporary shedding, (6) which is the most likely sort of hair loss that this plant could cause. 

Respiratory depression is always cited in connection to opioids, and the FDA has listed respiratory depression as a concern with kratom.  No toxicity or fatality dose data is available on kratom due to lack of scientific study, but risk for respiratory depression seems to be less than true opiates like morphine.  Available evidence shows almost all cases of kratom-related death involve one or more contributing compounds. (5)

While there is a lot of anecdotal data at this point, there is not a ton of conclusive scientific evidence around long-term effects of kratom use.

 

Conclusion?

There is promising evidence to suggest that the compounds found in the kratom plant could become the basis for a new generation of opioid-type drugs that are less addictive and less side-effect ridden. (4)

Many companies purport different psychoactive effects resulting from different strains of kratom.  This is mostly marketing in my opinion.  I have tried many different strains from all sorts of different companies and suppliers, and they all feel basically the same to me.  Of course that is just my opinion and maybe it's wrong.  The Maeng Da strains I've tried seem to be the most potent on a dry plant weight basis, but this too could just be my incorrect human perception.
