Siberian Cocklebur and Linagliptin

Here is the interaction we found between these two, with the evidence behind it.

Major

ANTIDIABETES DRUGS

Why this applies to Linagliptin

Linagliptin falls under ANTIDIABETES DRUGS — the group Siberian Cocklebur interacts with.

Siberian cocklebur seedlings and seeds have caused severe hypoglycemia in humans. Hypoglycemia occurs soon after consumption and worsens with time in most cases. Do not use Siberian cocklebur in people taking medications that also lower blood glucose.
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
Severity Major Likelihood Likely Evidence B

Well-controlled human studies have demonstrated the likely existence of this interaction.

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

Here's the concern with pairing Siberian cocklebur and linagliptin (Tradjenta). The cocklebur plant itself can lower blood sugar, sometimes dramatically. In people who ate the seedlings or seeds, severe low blood sugar set in soon after and tended to get worse over time. This isn't about cocklebur changing how your body processes linagliptin. It's simpler than that: both are pushing your blood sugar in the same downward direction at once.

Stacked together, you could be more likely to feel shakiness, sweating, a racing heart, confusion, or dizziness, the classic signs of a sugar that has dropped too far. Since cocklebur also carries real natural toxins, I'd be cautious here. Please don't change your linagliptin. Talk with your pharmacist or doctor before using cocklebur at all.

From our pharmacist’s overview on the Linagliptin page

“Linagliptin (Tradjenta) helps people with type 2 diabetes bring blood sugar down, so most of the 284 supplements and herbs on this page interact for one basic reason: they lower glucose too, and stacking them can drop you into hypoglycemia. I'd read this list with genuine care rather than a shrug.”

About Siberian Cocklebur

What is Siberian Cocklebur?

  • Nasal congestion and sinus problems
  • Allergic rhinitis (hay fever)
  • Headache
  • Skin conditions and itching
  • Joint and muscle discomfort

Siberian cocklebur is a fruit used in traditional Chinese and other Asian herbal medicine, mainly for nasal congestion, sinus issues, and allergies. Human evidence is very limited, and the plant contains naturally toxic compounds that can cause serious poisoning, so it should only be used under expert guidance, if at all.
