Do any natural products increase norepinephrine?

Factual Questions
1

I know that some natural products increase serotonin but here I am specifically asking for norepinephrine/noradrenaline. By “increase” I mean either increase the production or transfer or decrease the reuptake or elimination of norepinephrine.

By “natural products” I also include food and drink although I suspect that few do.

Is there a norepinephrine equivalent of the serotonin syndrome?

Yohimbine. Precursors like tyrosine or phenylalanine may work too.

Not really a product, but it is well documented that exercise increases norepinephrine.
