Why is Blue Lotus banned in some countries?

I was surprised to learn that Blue Lotus (Nymphaea caerulea) isn’t legal everywhere. In some countries it’s freely available as a tea or herbal extract, but in others it’s restricted or outright banned.

From what I’ve gathered, it’s not because Blue Lotus is dangerous in the same way as harder substances — historically it’s been used as a gentle aid for relaxation, dreaming, and spiritual practice. The issue seems to be more about how governments classify anything with psychoactive properties, even if mild.

Some places have grouped it under “narcotics” laws, while others have simply put it in a “grey area” where it’s not technically illegal, but not regulated for consumption either.

I’m curious:

• Does anyone know the exact reasoning in their country?
• Is it mostly about controlling plant medicines with any psychoactive potential?
• Or are there specific studies/politics that caused the ban?

It makes me wonder how we as a collective view plants that have been considered sacred for thousands of years, but get tangled up in modern legislation.
