Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with insulin (Myxredlin) and the dream herb. Insulin's whole job is to push your blood sugar down. Some animal studies suggest Calea zacatechichi may also lower blood sugar a little. So the worry is simple: the two effects could stack, and your sugar might drop lower than you expect. That could mean shakiness, sweating, a fast heartbeat, confusion, or feeling lightheaded.

I want to keep this in perspective, though. This is a theoretical concern based mostly on lab and animal work, not solid human studies, so we don't really know how strong it is in real life. If you do use this herb, it's smart to check your blood sugar a bit more often and let your doctor or pharmacist know before mixing them. Please don't change your insulin dose on your own.

About Calea Zacatechichi

What is Calea Zacatechichi?

  • Promoting vivid or lucid dreams
  • Sleep and relaxation
  • Digestive upset
  • Fever
  • Traditional ritual use

Calea zacatechichi, often called 'dream herb,' is a Mexican plant traditionally used to encourage vivid dreams and to treat digestive complaints and fever. Human research is very limited, so its benefits are not well proven, and its safety has not been carefully studied. It tastes very bitter, can cause nausea, and should be avoided during pregnancy and breastfeeding.

About Human Insulin Injection

What Is Human Insulin Injection Used For?

Brand name: Myxredlin

Novolin (human insulin injection) is used to improve glycemic control — meaning blood sugar management — in adults and children with diabetes mellitus.

Novolin 70/30 is a fixed-ratio mixture of intermediate-acting and short-acting human insulin. Because the ratio is fixed, it cannot be adjusted separately for background (basal) or mealtime (prandial) needs.
