Chaga Mushroom

Inonotus obliquus

Chaga is a woody medicinal mushroom traditionally prepared as a long-simmered tea. It’s best known for antioxidant content and immune-support marketing. However, chaga can be high in oxalates, which matters for people with kidney stone risk or kidney disease. Think of chaga as a periodic wellness tea, not a nonstop daily drink for everyone.

Key Benefits

Common Issues It May Help With

How To Use (Simple)

Taste / Notes

Earthy, woody, mild bitterness; sometimes vanilla-like notes.

Evidence Level

Strong traditional use and lab research on antioxidants; human clinical evidence for specific outcomes is limited. Safety considerations (oxalates) are important.

Cautions

Use caution if you have kidney disease or a history of kidney stones (oxalate content). Avoid during pregnancy/breastfeeding due to limited safety data. Use caution with autoimmune disease or immunosuppressants (immune activity).

Interactions

May increase bleeding risk with anticoagulants/antiplatelets (theoretical/limited evidence—use caution) If on immunosuppressants or have autoimmune disease, consult clinician before routine use If on diabetes medications, monitor blood sugar—some mushroom products can influence glucose markers
