Holy Basil and Dasiglucagon Hydrochloride

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Dasiglucagon Hydrochloride

Dasiglucagon Hydrochloride falls under ANTIDIABETES DRUGS — the group Holy Basil interacts with.

Theoretically, holy basil might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Small clinical studies show that taking holy basil can decrease fasting blood glucose and other measures of glycemic control in patients with type 2 diabetes.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's a little wrinkle worth understanding. Dasiglucagon (Zegalogue) is your rescue medicine for severe low blood sugar. It works the opposite way of most diabetes drugs, by telling your liver to dump stored sugar into your blood and pull you out of an emergency. Holy basil, on the other hand, tends to gently lower blood sugar, based on a few small studies in people with type 2 diabetes.

So they push in opposite directions. The realistic concern isn't that they cancel each other in the moment, but that regularly taking holy basil could nudge your blood sugar lower overall, possibly setting up more of the very lows that dasiglucagon treats. The evidence here is modest, so don't panic. Just mention the tulsi to your pharmacist or doctor so they can keep an eye on your numbers.

“Dasiglucagon (Zegalogue) is an emergency injection that rapidly raises blood sugar during a severe diabetic low, so a supplement list this large deserves genuine care. All 239 interacting ingredients act through blood glucose, and most of them lower it, deepening the very crashes this drug exists to reverse.”
