Doctor Z’s was started by a couple of ER doctors in Portland, Oregon who were looking for a way to help frequent marijuana users who develop nausea and vomiting.

It turns out many people experience a condition called cannabinoid hyperemesis syndrome, or CHS.  In some people, marijuana causes uncontrollable nausea, vomiting, and abdominal pain that is resistant to conventional treatments.  The usual medicine we use to treat vomiting just doesn’t seem to work.  In fact, through trial and error people with CHS found that the only thing that seemed to help was soaking in a hot shower.  People would come to the ER as a last resort after literally emptying out their hot water heaters.Doctor Z’s co-founder grew up in Oregon.  “I’ve been around marijuana all my life. It’s a great drug, but sometimes it goes awry and people who smoke a lot develop severe nausea and vomiting.   If you smoke marijuana frequently and you’ve had abdominal pain or vomiting that gets better with a hot shower or bath, you’ve probably had CHS.  As ER doctors in Portland we see it frequently, and unfortunately most medications are ineffective in treating it.”


The frustrating thing for Doctor Z’s founders was that previously ER doctors were unable to effectively treat CHS.  “We gave all of the nausea medications available and people still felt bad”. Fortunately, somebody realized that capsaicin applied to the skin might work the same way as hot water does to alleviate nausea.  Several studies and years of treating patients showed that this works. The trick was getting the right strength where you could treat the nausea and abdominal pain with a concentration of capsaicin cream that wasn’t too irritating on the skin. Through trial and error Doctor Z’s developed the right strength of capsaicin cream to provide relief and feel great on the skin.  Striving to make the cream even more effective, Doctor Z’s went a step further and added  all natural essential oils that were known to help with nausea, such as lemongrass, peppermint, bergamot, and cardamom. 

It’s extremely rewarding to give people a product of the highest quality that smells great, feels good, and is so effective at treating their symptoms without all the side effects of prescription medications. And, since it’s available over the counter, people can use it at home and hopefully never have to meet Doctor Z’s founders in the ER.

We’re happy that we could come up with a product that’s as good as the weed we have here in Portland.
