“I had no clue about this” is a common way of saying:
“I didn’t know this before.”
“This information is new to me.”
“I was surprised to learn this.”
For example:
- I had no clue that peppermint tea could worsen heartburn.
- I had no clue that hibiscus tea might affect blood pressure.
It’s an informal expression often used when someone learns something unexpected or interesting. 😊
