In its December newsletter, the San Benito County Opioid Task Force warned about the dangers of the drug Kratom and its derivative 7-hydroxymitragynine (7-OH).

Mary White, San Benito Public Health pharmacist, said Kratom (Mitragyna speciosa) and 7-OH is an extract from leaves of a tree native to Southeast Asia. It is taken in capsules, powder, or tea, and used for both stimulant and opioid-like effects. 

“It is marketed as a natural product for brain boosting, depression and a variety of other things and not made clear what this really is,” White said.  

The product on the market, she said, has a highly potent opioid effect since it has a high concentration of 7-OH and there were several fatalities from the drug in Los Angeles in 2025.

According to the U.S. Food and Drug Administration (FDA), Kratom is a tropical tree (Mitragyna speciosa) native to Southeast Asia. 

Products prepared from Kratom leaves are available in the U.S. online and in stores. 

Kratom is often used to self-treat conditions such as pain, coughing, diarrhea, anxiety and depression, opioid use disorder, and opioid withdrawal, with regular Kratom users self-reporting using less than 6g of botanical kratom per consumption, according to several studies. 

An estimated 1.7 million Americans aged 12 and older used Kratom in 2021, studies found.
