All you need to know about Rhynchophylline – An alkaloid in Kratom

If you're delving into the world of Kratom, you've probably encountered numerous discussions about its various alkaloids and their effects. While some, like mitragynine, take the spotlight, others play a subtle yet significant role. Among the latter is rhynchophylline, an alkaloid that adds depth to the kratom experience. 

In this article, you’ll learn more about rhynchophylline, uncover its properties, and understand its significance within the realm of Kratom.

What is Rhynchophylline?

Source: Wikipedia 


Rhynchophylline is an alkaloid found in specific plants like Uncaria rhynchophylla and Uncaria tomentosa. It's also present in the leaves of Mitragyna speciosa, better known as Kratom, a plant native to Thailand. 

To understand the role of rhynchophylline in Kratom, it's best to start with the basics. Rhynchophylline is one of the naturally occurring alkaloids found in Kratom. It belongs to the same family of alkaloids as other well-known compounds found in the same plant, like mitragynine, mitragynine pseudoindoxyl, and 7-hydroxymitragynine. Chemically, it's similar to mitragynine, since both alkaloids share structural features with controlled opioids. 

Like its counterparts, rhynchophylline possesses unique properties that contribute to the overall Kratom experience. 

The role of Rhynchophylline

Blood pressure regulation: One of the standout features of rhynchophylline is its potential to assist in regulating blood pressure. So far, research shows that it has vasodilation properties, which means it may help widen blood vessels, consequently reducing blood pressure. This attribute sets rhynchophylline apart and showcases its potential benefits.

Smooth muscle relaxation: Rhynchophylline's effects extend to muscle relaxation, making it valuable in certain Kratom strains. It contributes to the calming and soothing properties found in particular Kratom varieties. For those seeking relaxation without excessive sedation, rhynchophylline plays an essential role.

*It’s important to mention that research is still ongoing, and the effects of rhynchophylline are still being tested.

Strain variability


Just like other Kratom alkaloids, rhynchophylline contributes to the diversity of Kratom strains. Different strains, including red, green, and white vein varieties, have unique properties and effects. Rhynchophylline, along with other alkaloids, influences these distinctions, adding to the complexity of the Kratom experience. Strains with greater rhynchophylline percentage can potentially help with sleep disorders.  

Potential benefits

Some studies report that rhynchophylline may provide mood-enhancing and relaxing effects. However, more research is needed to understand and confirm these potential benefits fully.

Is rhynchophylline the same as mitragynine?

No, rhynchophylline is a distinct alkaloid, but it shares the same alkaloid family with mitragynine, one of the primary compounds in Kratom.

Can I find rhynchophylline in other plants or substances?

Rhynchophylline is primarily found in the leaves of the Mitragyna speciosa tree, commonly known as Kratom. But you can also find it in Uncaria rhynchophylla and Uncaria tomentosa.

What are the potential effects of rhynchophylline?

While research is ongoing, rhynchophylline is thought to contribute to mood enhancement and relaxation, though its effects are milder compared to other Kratom alkaloids.

How can I maximize the benefits of rhynchophylline in Kratom?

Using Kratom strains with higher rhynchophylline content may enhance the effects associated with this alkaloid. However, the effects of rhynchophylline are still under investigation.

Is rhynchophylline safe to use?

Kratom and its alkaloids, including rhynchophylline, should be used with caution. It's essential to follow recommended dosages and consult with a healthcare professional, especially if you have any underlying health conditions or are taking other medications.
