Yes, sorry, I don't know any more detail. I assume herbs and spices count. After all, they are medicinal :) Pickled ginger goes well with anything.

Not so hard to get to 30, especially with Asian food. My expertise such as it is is with Thai and Indian. These involve complex flavours with easily a dozen things in a single dish.
The kimchi I made last month has 9 ingredients; tonight's raita contains 6. Even the packet Indian curry with no artificial ingredients has 13. Plus fish and the oil it was cooked in gets you to 15.

That is all not counting Himalayan salt which is said to contain 84 minerals.
