Chaga and Lymphocyte Immune Globulin

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Lymphocyte Immune Globulin

Lymphocyte Immune Globulin falls under IMMUNOSUPPRESSANTS — the group Chaga interacts with.

Theoretically, chaga might interfere with immunosuppressive therapy.
In vitro research suggests that certain constituents of chaga stimulate immune function. This has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

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

Here is the basic idea with Chaga and Atgam (lymphocyte immune globulin). Atgam is given in the hospital to quiet down your immune system, usually around an organ transplant or for certain blood disorders. Chaga, on the other hand, is thought in lab studies to do the opposite and rev the immune system up. So the worry is that Chaga could work against what Atgam is trying to do, possibly making the medicine less effective at preventing rejection.

I want to be honest with you though: this is a theoretical concern based only on test-tube research, not anything seen in actual patients. Still, since Atgam is serious medicine for a serious situation, I would not add Chaga on your own. Please run it by your transplant team or doctor first.

About Chaga

What is Chaga?

  • Immune support
  • Antioxidant support
  • General wellness/tonic
  • Blood sugar support
  • Inflammation

Chaga is a fungus that grows mostly on birch trees and is used as a tea or supplement, mainly for immune and antioxidant support. Human evidence for its benefits is very limited, and it may raise some safety concerns such as effects on blood sugar, bleeding, and kidney stones. Talk with your pharmacist or doctor before using it, especially if you have a health condition or take other medicines.
