about kratom

What is kratom?

Kratom is the dried, ground leaf of Mitragyna speciosa, a tropical evergreen tree native to Southeast Asia. The leaves contain a family of alkaloids — mitragynine and 7-hydroxy-mitragynine being the two best-studied — that have made kratom a traditional botanical for centuries in Indonesia, Malaysia, Thailand, and Papua New Guinea.

The tree itself is a member of the coffee family (Rubiaceae). Commercial kratom is made the old-fashioned way: mature leaves are hand-harvested, de-stemmed, dried, and milled into a fine powder. Almost everything that distinguishes one kratom product from another, the vein color, the strain name, the grind, comes down to when the leaf was picked and how it was dried.

Red, green, and white vein kratom — what's the difference?

The vein color refers to the color of the leaf's central vein at harvest, which corresponds loosely to the leaf's maturity. The same tree can produce all three depending on when the leaf is picked and how it's dried.

  • Red vein — the most mature leaves, typically dried the longest.
  • Green vein — harvested mid-maturity, between red and white; often the everyday pick.
  • White vein — younger leaves, often dried indoors away from light.
  • Specialty / yellow — usually a blend or an extended-drying technique. Each shop's specialty is its own thing.
Infographic: kratom vein colors explained. Red vein comes from fully mature leaves with the longest drying time, green vein from mid-maturity leaves dried indoors then finished in the sun, white vein from young leaves dried indoors away from sunlight. All three come from the same tree, Mitragyna speciosa.

Kratom strains: Maeng Da, Bali, Hulu, Sumatra

Strain names refer to the region of origin or the cultivar lineage, not the alkaloid profile directly. Maeng Da ("pimp grade" in Thai) is a marketing term that's come to mean a high-alkaloid select. Bali, Sumatra, Malay, and Hulu Kapuas all reference geographic origin.

We don't claim that any one strain is "stronger" or "better" — alkaloid content varies batch to batch. That's why we lab-test our kratom and post the report on request.

How kratom strain naming actually works

Put the two systems together and you can read almost any kratom label. The first word is usually the vein color (red, green, white). The second is the origin or lineage: Bali, Malay, Sumatra, Hulu Kapuas, Thai. So a Red Bali is mature, longer-dried leaf in the Bali style, and a Green Hulu is mid-maturity leaf from the Kapuas Hulu river region of Borneo. A strain name tells you two things, what the leaf looked like at harvest and where or how it was grown. That's all it tells you.

What a name does not describe is an outcome. There's no governing body making sure one vendor's Red Bali matches another's, and alkaloid content shifts with soil, season, and drying technique even within a single region. Two bags with identical names can be very different leaf. That's why the batch matters more than the name, and why a good vendor should be able to tell you something concrete about the specific lot you're buying.

What our kratom lab panel screens for

Third-party accredited labs run the panel; we never test our own kratom in-house.

"Lab tested" gets stamped on a lot of kratom without much behind it, so here is specifically what our panel covers:

  • Identity and potency: confirms the material is genuine Mitragyna speciosa and quantifies the mitragynine and 7-hydroxymitragynine content.
  • Heavy metals: lead, arsenic, cadmium, and mercury, measured against FDA action levels.
  • Microbial contamination: total plate count, yeast and mold, salmonella, and E. coli.

Testing is performed by third-party, ISO/IEC 17025 accredited laboratories, not by us in-house, which is the arrangement you should want. Certificates of analysis are available on request: request a COA and we'll send the lab report for your product.

Kratom grind and packaging: what to look for

What you want to see: a fine, even grind and a fresh green color, with no stem-and-vein chunks.

You can learn a lot about kratom before a lab ever sees it. Well-processed powder is milled fine and consistent, with an even color and no visible chunks of stem or vein (stem and vein material bulks up weight but isn't leaf). It should smell green and planty, never musty; a damp or sour smell suggests the leaf wasn't dried properly, which is exactly the condition that lets mold take hold.

Packaging matters just as much, from any vendor. Look for a sealed, light-blocking bag with a clear product name and a lot or batch identifier printed on it. That little lot code is what lets a COA be matched to the actual bag in your hand; without it, a lab report is just a nice PDF. We sift and package our kratom in-house at our Portland shop and label it by hand.

Where to buy kratom: how to vet any vendor

There is a great deal of kratom for sale online, and almost none of it comes with a lab report attached. So the real question isn't where to buy kratom — it's who will show you their work. We'd rather you buy from a careful competitor than a careless anybody. Wherever you shop (including here), ask these questions before you order:

  • Can you show me a COA? The answer should be yes, quickly, from a third-party accredited lab, and the report should be recent and reference a lot number you can match to your product.
  • Where does the kratom come from? A vendor should be able to name the country and region of origin and describe how the leaf gets from grower to shelf. Vague answers usually mean a reseller who has never seen the supply chain.
  • Do you verify age? Responsible vendors enforce an age minimum at purchase (we require 21+). A shop that will sell to anyone with a card isn't running the rest of its business carefully either.
  • What food-safety practices do you follow? Ask about HACCP food-safety protocols, and whether any certification body (like a state department of agriculture) has actually inspected them.
  • How do you handle state restrictions? Kratom is banned in a handful of states. A vendor willing to ship there anyway is telling you how they treat the rules in general.

How we source & test our kratom

Our kratom comes through our Portland shop and is tested for heavy metals, microbial contamination, and alkaloid content (mitragynine + 7-hydroxy-mitragynine). We're certified by the Oregon Department of Agriculture and follow HACCP food-safety protocols. Certificates of analysis are available on request — ask us and we'll send the lab report for your product.

A note on kratom use

We sell kratom for educational and research purposes only. The FDA has not evaluated kratom for any therapeutic use, and we can't legally make health claims. Do your own research, talk to a healthcare practitioner, and never combine with other substances without medical guidance. Must be 21+ to purchase.

concentrates

Kratom extracts

A kratom extract is concentrated Mitragyna speciosa: dried leaf reduced down so that a small amount of extract carries the alkaloids of a much larger amount of leaf. That's why extracts are measured in grams and sold in small jars while powder is sold by the ounce and kilo. We carry two extract tiers. Gold Reserve kratom extract is our mid-tier, with a stated 8.69% mitragynine concentration, and Black Reserve kratom extract is our strongest at 16% total alkaloids. Both are sold in 1 g and 10 g sizes. If you want a liquid format instead, the Basic Plant kratom shot is a ready-bottled liquid standardized to a fixed alkaloid content per bottle.

capsules

Kratom capsules

Capsules are the same milled leaf as our loose powder, pre-measured into a cap.

Kratom capsules are not a different product, they're a different package. Our capsules are pre-filled with the same milled leaf we sell as loose powder; the material is identical in both formats. Capsules cost a little more per ounce for the filling work, and powder gives you the better bulk price, so it comes down to convenience versus economy. Most of our strains come in both formats, including Green Maeng Da capsules, Red Bali capsules, and White Maeng Da capsules. Prefer to fill your own? We also carry empty gelatin and vegetable capsules and capsule-filling machines in our accessories section.

shipping

Where we ship kratom

Kratom is legal in most of the United States, and we ship it to every state where it's allowed. A handful of states ban it outright, and our checkout enforces that list automatically, so a restricted address gets flagged before you can pay. As of 2026-07-09, we cannot ship kratom to these 10 states:

  • Alabama
  • Arkansas
  • California
  • Connecticut
  • Indiana
  • Kansas
  • Louisiana
  • Tennessee
  • Vermont
  • Wisconsin

One partial exception: due to Oregon state regulations, we can't ship Red Vein and Green Vein kratom to Oregon addresses. Our white vein, yellow vein, and specialty kratom ship to Oregon without issue.

A few cities and counties also restrict kratom even though their state allows it, currently in Colorado, Florida, Idaho, Illinois, Massachusetts, Mississippi, New Hampshire. Checkout blocks the banned cities we can verify from your address; county-level rules are worth double-checking yourself. The full list of localities lives on our shipping restrictions page.

kratom faq

Kratom FAQ

Is kratom legal where I live?
Kratom is legal in most U.S. states, but a few states and some cities and counties restrict or ban it. We don't ship kratom anywhere it's prohibited, and checkout will flag a restricted address. See our shipping page for the current list.
How is your kratom tested?
Our kratom is screened for heavy metals (lead, arsenic, cadmium, mercury), microbial contamination (yeast, mold, salmonella, and E. coli), and alkaloid content (mitragynine and 7-hydroxymitragynine). We're certified by the Oregon Department of Agriculture and follow HACCP food-safety protocols.
Can I get a certificate of analysis (COA) for my kratom?
Yes. We keep COAs on file. Request the lab report for any product you've ordered and we'll send it over.
What's the difference between red, green, and white vein kratom?
Vein color refers to the color of the leaf's central vein at harvest, which tracks loosely with leaf maturity. Red is the most mature, green is harvested mid-maturity and the most balanced, and white comes from younger leaves. The same tree can produce all three.
What does "Maeng Da" mean?
Maeng Da ("pimp grade" in Thai) is a marketing term for a high-alkaloid select, not a region. Names like Bali, Sumatra, Malay, and Hulu Kapuas refer to geographic origin or cultivar lineage, not a guaranteed alkaloid profile.
How should I store kratom?
Keep kratom in a sealed container away from heat, light, and moisture. Stored cool and dry, the powder holds its color and aroma for a long time.
Is it legal to buy kratom online?
That depends on your state. Kratom is legal to buy online in most of the U.S., but 10 states ban it and a few cities and counties restrict it locally. We enforce every restriction at checkout, so if we can ship to your address, the order is legal on our end. The full state list is in the "Where we ship kratom" section above.
Which states can't you ship kratom to?
We currently can't ship kratom to Alabama, Arkansas, California, Connecticut, Indiana, Kansas, Louisiana, Tennessee, Vermont, or Wisconsin, and Oregon state regulations keep us from shipping Red Vein and Green Vein kratom to Oregon addresses. A few cities and counties restrict it too; see our shipping restrictions page for the complete list.
How fast do you ship kratom?
Orders ship within 24 hours of being placed. Tracking is emailed when it leaves the shop; we don't ship Sundays or holidays. Details on our shipping page.
Do you sell kratom in bulk?
Yes. Bulk kratom is what we do — every strain is sold loose by weight in larger sizes, so the per-ounce price drops as the size goes up. Powder gives you the best bulk value. It's all hand-packed and lab-tested the same way, whether you buy an ounce or a kilo.
How do I buy kratom online from Herb Stomp?
Pick a strain, choose a size from a single ounce up to a kilo, and check out. Every kratom for sale on this page is hand-packed in our Portland shop and ships within 24 hours to any state where kratom is legal. Checkout flags restricted addresses automatically, and you can request a COA for anything you order.
Where can I buy kratom near me?
If you're in Oregon, our Portland shop at 5700 NE Sandy Blvd is open Monday to Friday, 10am–7pm, and Saturday, 12pm–7pm, and stocks every strain we sell online. Everywhere else, a search for kratom near me usually turns up a shop that can't show you a lab report. We ship within 24 hours to every state where kratom is legal, and you can request a COA for anything you order.

Holy moley. Kratom saved my life around 8 years ago. With severe chronic pain, the doctors had doped me up RX opiates for years. When I lost my insurance.. The inevitable happened, as it does for far too many. My life was destroyed very quickly, mostly by my own hand. Lost, hopeless, scared, angry... I finally found…

Herb Stomp (Sandy) is BY FAR the best Herb and Kratom store I have ever been to. In my 2.5 years of using Kratom, I have never been to a place as helpful as this! The employees are so so helpful! Usually when buying Kratom, I’m met with grumpy head shop owners who seem to want me to either spend out of my budget, or…

I moved this month from NW Portland to SE and have dealt with stores that sell kratom in many states across the U.S. and online for the last couple of years. I found the prices of kratom at Herb Stomp to be about 1/3 of the price and ~4x the amount of which I had been paying! The store offered $2 sample bags which I…
