Study: Kratom alkaloid make-up dependent on genetics, environmental factors, and processing

A new study published in Frontiers in Plant Science is presenting a clearer picture of how post-harvest processing changes the plant’s chemistry. The researchers from University of Florida and Oregon State University compared kratom varieties grown in Hawaii and Malaysia to see how factors like withering time, drying temperature, and harvest season influence alkaloid profiles—particularly …

Review Finds Insufficient Evidence of Severe Health Risks From Kratom Alone

Important to note: This does NOT mean severe health risks from kratom alone do not exist. There is a toxic amount of any substance that can be ingested, including kratom. The majority, but not all, of toxic adverse events associated with kratom have involved other substances, as well as substance misuse in general. Kratom should …

Dr. McCurdy at Kratom Debate: Natural Leaf is “the only product that should be in the marketplace”

The kratom industry is railing against 7-OH products as problematic, but are extra-strength kratom extracts problematic too? The controversy surrounding the rise of new 7-hydroxymitragynine (7-OH) products has sparked a debate among various players in the kratom industry, as well as scientists and consumers. A debate called “The 7-OH Fault Line” took place at the …

Preliminary in silico Study Explores Kratom Alkaloids’ Effects on Breast Cancer Protein

Disclaimer: Kratom Is Not a Breast Cancer Treatment: While this study investigates the potential of kratom compounds mitragynine and 7-hyroxymitragynine to bind with HER2 receptors through computer modeling, it does not prove or suggest that kratom cures breast cancer. These results are preliminary and based solely on in silico simulations (i.e., computer-generated predictions). No clinical …

Study: Mitragynine Stimulated and 7-Hydroxymitragynine Depressed Respiratory Activity in Rats

Disclaimer: Preclinical studies on compounds’ effects on test animals do not always demonstrate exactly how compounds will affect humans A new study in rats examined the respiratory effects of mitragyinine (MG), considered the main compound in most kratom leaves consumed by users, and 7-hydroxymitragyinine (7-HMG) that occurs in very trace amounts in dried kratom leaf …

Nefarious Marketing: Making Health Claims and Synthetics Sold as “Kratom”

Health Claims in Texas Smoke Shops With a dearth of regulation and market enforcement, marketers of kratom, kratom-derived synthetics, and products like hemp and THC continue to employ shady business practices to sell their products. Researchers from university pharmacy and medicine departments conducted a secret shopper investigation at 100 smoke shops in San Antonio and …

Study Shows Kratom Leaves Attacked by Insects Have Higher Mitragynine

Read the full study, where the above image can be found: https://pmc.ncbi.nlm.nih.gov/articles/PMC12040156 Researchers at Kasetsart University and Chulalongkorn University in Bangkok, Thailand found that when insects like beetles, butterflies, and true bugs feed on kratom, the plant produces more mitragynine as a defense mechanism. This increase is also linked to higher leaf acidity. Plants produce …

Johns Hopkins Seeks Participants for Online Study on 7-OH Kratom Products

The Johns Hopkins University School of Medicine is conducting a groundbreaking online study on 7-hydroxymitragynine (7-OH), a compound associated with certain kratom products. The study invites individuals who have consumed 7-OH products to participate by completing a screening process and, if eligible, an online survey about their usage patterns. As a thank-you, participants who complete …
