Here is the interaction we found between these two, with the evidence behind it.
ANTITHYROID DRUGS
Why this applies to Carbimazole
Carbimazole falls under ANTITHYROID DRUGS — the group Bamboo interacts with.
Animal research suggests that long-term consumption of bamboo shoot can decrease thyroid peroxidase activity, as well as levels of thyroxine (T4) and triiodothyronine (T3). This effect has not yet been reported in humans.
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.
Here's the gist: carbimazole works by dialing down how much thyroid hormone your gland makes, which is exactly what you want when your thyroid is overactive. Bamboo, at least in animal studies, seems to nudge things in the same direction by lowering thyroid hormone production too. So in theory, stacking the two could push your thyroid too low, a state called hypothyroidism.
If that happened, you might notice fatigue, weight gain, feeling cold, dry skin, or sluggish mood. I want to be honest though, this is theoretical and based only on animal research, with nothing confirmed in people yet. Food-amount cooked bamboo shoots are unlikely to matter much; concentrated daily supplements are the bigger question. Before adding a bamboo supplement, run it by your pharmacist or doctor so your thyroid levels can be watched.

From our pharmacist’s overview on the Carbimazole page
“Carbimazole (Neo-Mercazole) calms an overactive thyroid, and since the drug itself can occasionally stress the liver, most of the supplements on this list earn their place by carrying liver toxicity of their own. Doubling up on liver stressors is the risk I take most seriously here, and the major-rated entries deserve a careful read fi…”

About Bamboo
What is Bamboo?
- Source of silica for hair, skin, and nails
- Bone and joint support
- General nutrition (cooked shoots as food)
- Antioxidant support
- Traditional digestive remedy
Bamboo is a giant grass whose shoots are eaten as food and whose leaves and silica-rich extracts are sold as supplements, often for hair, skin, nail, and bone support. Solid human evidence for these benefits is limited, and raw shoots must be properly cooked because they contain natural compounds that can release cyanide. Talk to a pharmacist or doctor before using bamboo supplements, especially if you have thyroid problems or are pregnant.
