What is ginkgo leaf? Can I take it continuously?

I was prescribed medication for acute hearing loss for a month.

After taking steroids for about 1 to 2 weeks

After that, take a tinamine tablet called Ginkgo Leaf.

They keep prescribing it because it is not a medical product.

The effect is good, but it needs to be taken more continuously.

I wonder if it will be good.

I want to take it more because the relapse rate is high.
