What’s in the the kava plant?

Picture of Kavahana

Kava, known for its calming and relaxing effects, originates from the south pacific islands. It’s been used culturally for centuries in religious and traditional ceremonies to honor guests and bring community together. It’s also been used to treat a variety of medical conditions both topically, internally and emotionally.

Traditionally taken as a tea-like beverage, it comes from the dried roots of the pepper plant; piper methysticum, which are ground down into a powder and steeped in water.

For those who have used kava for a while, this is old news. But have you ever thought about the plant itself? And different aspects of it that create the effects that have come to know and love?

Other names kava goes by

Like many things that have origins in different places, the kava plant goes by many different names depending on where it’s coming from or where you’re drinking it.

Some of these other names are:

Kava kava

Kawa kawa








Where it grows

Kava is found in the pacific islands. It likes to grow at altitudes 150 -300 meters (490-985 feet) above sea level and prefers rocky ground that drains well in rainy climates. It can grow up to 6 meters (20 feet) tall but when grown, is usually harvested at 2- 2.5 meters (6.5- 8 feet) tall.

Interestingly, kava doesn’t have seeds, so it relies only on its roots to spread and grow new plants.

Key parts of the kava plant

There are three key parts to the kava plant: the leaves, the stem and the roots and rhizomes. Traditionally, the root and rhizomes is what kava is most valued for the drink. This is where the highest level of kavalactones and flavokavains are located giving kava its well known effects. 

The stem and peelings are usually used to grow new kava plants. They are also sometimes mixed with the roots to make beverages, however their high alkaloid content makes the toxicity level high. 

And finally the leaves. The leaves are not typically used for beverages in the same way the roots are. However they have strong antimicrobial and anti-inflammatory properties making them useful in treating headaches, skin irritations, and rashes. The leaves, like the stems, have high levels of alkaloids so should be used with caution.

The two root sections

Kava has two different sections to its roots; 

Crown roots 

Lateral roots

Crown roots are larger parts of roots that can be harvested as “kava chips”. These make up about 80% of kava’s roots. Lateral roots are smaller and branch out from the crown roots. They are about 20% of kava’s roots but have the highest level of kavalactones. Because of this, they are considered the most valuable kava and are usually reserved for only the premium level products.


These are the active ingredients of the plant. There are 18 different kavalactones, but only 6 are known to be players in the effects of kava. These are:

Desmethoxyyangonin (DMY)

Dihydrokavain (DHK)

Yangonin (Y)

Kavain (K)

Dihydromethysticin (DHM)

Methysticin (M)

Each of these shows up in different levels in each kava plant and has different effects and feelings associated with it.

The different kava plant strains and chemotypes

There are 75 known kava strains all linked to the country they come from. There are 8 origin countries of kava: Fiji, Hawaii, Vanuatu, Tonga, Samoa, Micronesia, Papua New Guinea and French Polynesia. Each strain from each of these countries has slightly different effects. This is due to the kavalactones present and the chemotype of each kava cultivar or strain.

The chemotype refers to the chemical make-up of the plant. Scientists will look at the different levels of different kavalactones in each plant and list them in order of prevalence. For example, if a plant has the chemocode 346125, we know that Yangonin (3)  is the highest strain,  then Kavain (4), and Methysticin (6) and so on. This creates a unique chemocode for each plant. 

Knowing kava strains and chemocode groups help you better understand the kava plant you may want for the experience you are looking for.
