Understanding 7hydroxymitragynine: A Powerful Alkaloid in Kratom

Kratom, a tropical tree native to Southeast Asia, is a globally noted unique substance for its effects and potential benefits. 7hydroxymitragynine is one amongst many alkaloids present in kratom leaves that is highly potent. Most of the times in the smallest amounts, this alkaloid from kratom is responsible for the psychoactive and pain-relief qualities of the plant.

What is 7hydroxymitragynine?

7hydroxymitragynine is a naturally occurring indole alkaloid found in the kratom plant (Mitragyna speciosa). It is considered to be one of the most potent active compounds in kratom, known for its strong affinity for the mu-opioid receptors in the brain. The 7hydroxymitragynine presence is less than 0.05% in total contents of alkaloid in most kratom strains but it exhibits greater potency than its precursor, mitragynine.

Some studies have even gone as far as to say that 7hydroxymitragynine is more potent than morphine as an analgesic. Therefore, it is targeted by researchers on new forms of pain control.

How Does 7hydroxymitragynine Work?

When taken, the main alkaloid of kratom, namely mitragynine, undergoes hepatic metabolism to form 7hydroxymitragynine, a metabolite that interacts with the opioid receptors, particularly the mu-opioid receptor, with roles in pain modulation, mood, and euphoria.

Unlike in the case of classical opioid ligands causing considerable respiratory depression-a secondary reason to overdose by synthetic opioids-7hydroxymitragynine is not said to produce cardinal respiratory depressions. But this does not mean it is completely safe. Inasmuch as the opioids act on a certain system in the body, dependence and withdrawal symptoms may be brought on by heavy or continuous use.

Is 7hydroxymitragynine Safe?

It remains to be seen whether 7-hydroxymitragynine is really safe or not. While many claim to benefit from kratom for pain relief, enhancement of mood, or energy infusion, 7hydroxymitragynine’s long-term repercussions remain debatable. The FDA of the United States has raised concern on the potential abuse of kratom, though it is legal in numerous states and countries.

Most of the controversy surrounding kratom has been focused on the powerful effects of 7hydroxymitragynine. Because of its strength, it is largely responsible for the effects-aesthetic as well as adverse-that kratom produces. That said, kratom should be used with caution, especially if the consumer is considering concentrated extracts, as there could be more of this compound present.

Final Thoughts

If someone is a kratom user, has a passion for health, or is merely an interested researcher, knowing about 7hydroxymitragynine is imperative. This alkaloid is a major player in the unique syndrome that kratom presents; it has promising potential but must be approached with respect and responsibility.

Hopefully, as more scientific research comes forth, a much clearer picture will paint how 7hydroxymitragynine can be employed safely and beneficially. In the meantime, however, when dealing with natural substances such as kratom, moderation and education go a long way.
