How is harmala processed by the liver?

How is processed harmala + DMT orally?

The reason for this question is that my husband just recovered from hepatitis A. It was serious sh**, so we have to know how to move on from this.

He hasn't done liver enzymes blood work yet, but soon he will.

Also if micro dosing harmala, would that be a problem?

Any thoughts, On the web I couldn't find any article, but one long paper,250 pages, full of charts... No help of any kind.

Thank you
