Kratom, Explained

Kratom, explained.

Bali, Borneo, Maeng Da… what do those names actually mean?

Start with the name.

Most are place-based names. Others are trade names used by sellers.

Bali
A name referring to Bali, Indonesia.
Borneo
A name referring to the island of Borneo.
Malay
A name referring to Malaysia.
Thai
A name referring to Thailand.
Indo
A name commonly referring to Indonesia.
Maeng Da
A trade name, not a standard strength or quality grade.

The name alone can’t tell you how strong a product is or how it will feel.

A place name also doesn’t prove where that batch was grown.

What about red, green & white?

RED = color label
BALI = product name

That’s how to read “Red Bali.” It isn’t a recipe or a strength rating.

Common marketing descriptions

Red

“Calming” or “relaxing”

Green

Descriptions vary, from stimulating to calming.

White

“Energizing” or “stimulating”

These are marketing descriptions, not reliable predictions. Products vary, and people can respond differently.

The product type matters.

  • Plain leafDried or ground kratom leaf. Natural doesn’t mean risk-free.
  • ExtractConcentrated compounds. Strength varies between products.
  • Added or enhanced 7-OHPotent opioid products that differ from plain leaf. FDA advises avoiding them.

Know the risks.

Kratom can cause dependence, withdrawal, nausea or dizziness. Rare but serious reported harms include seizures and liver problems. Mixing it with other drugs can increase risk.

FDA warns against kratom use. No kratom product is FDA-approved for medical use. Taking medicines? Ask a healthcare professional about interactions.

How do I read a lab report?

A certificate of analysis (COA) reports tests on a sample. Check:

  • The product and lot or batch number match the package.
  • The laboratory identity, sample date, and report date are shown.
  • Alkaloid results specify the compound and units. mg/g or percent describes concentration; mg per serving refers to a defined serving.
  • Contaminant results identify what was tested, such as heavy metals and harmful microbes—not only a “pass” badge.

A COA does not prove safety, medical effectiveness, or that every possible contaminant was tested.

More background & sources

Kratom comes from the Southeast Asian tree Mitragyna speciosa. Its leaf compounds interact with opioid receptors. Product names can sound precise, but they do not reliably predict strength, safety, or effects.

7-OH means 7-hydroxymitragynine. It occurs naturally in trace amounts in leaf; products with added or enhanced amounts are different.

One survey found color-related reports without significant matching alkaloid differences in tested products. It was unblinded and mostly involved one vendor. Botanical studies show real variation, including differences with leaf development. Neither finding validates retail names as reliable effect guarantees.
