Ginger for a short term relief

Hi all,
New here, and unsure if I suffer from Meniere's or something else, as I also have MAV and eye problems which makes it more difficult for the doctors to diagnose. Whatever it is, I've been having it for at least 10 years by now.
Started JOH about a week ago, hoping for some results.
Wanted to share with you my short term solution, which I'm using for about a year now - Fresh ginger root.
I cut a piece about the thickness of the index and middle finger, and about the little finger lengthwise (can take a picture if needed), peel the skin, and grate it. Then put it in a cup with boiling water and drink it, can be mixed with tea.
Relief comes within 10 minutes, for the next two hours or so. Not a cure for MM, but really helps me get through the day, especially when I'm having bad vertigo.

A few notes I noticed over time:
-Strong colored ginger is really spicy, not in a good way. And possibly a bit less effective.
For example I'll put random pictures from google:

Bad: https://cdn.apartmenttherapy.info/i...hive/65f47aea0bd2c273dc6c4d23901c06eac5d672ec
-If you don't mind, you can eat it once you finish drinking, seems to double the effect (but definitely not necessary).
-You can cook it by keeping the water boiling for about 5 minutes, seems to extract all of the contents, since there's no flavor left in the grated ginger after cooking. Personally I don't like the smell, I don't think it's more effective than eating the grated ginger after drinking, and it's a waste of time.
-Don't freeze the ginger root, it seems to lose it's effectiveness after freezing.
-I have no idea why it works, and if there are any negative long term effects to consuming large amount of ginger. Haven't found much info.
