Tinnitus has many possible causes. If you can clearly identify the root cause, it can be much simpler to treat. But even if you cannot, there are some good naturopathic symptomatic therapies to try.

Nitric oxide is often viewed as a beneficial compound for its role in promoting blood flow, but this is far from universally the case. Another even more ubiquitous gas, CO2, is far more commonly used for this purpose... and baking soda is one quick and easy way to increase it.

Monk fruit is a natural alternative sweetener that not only has no calories, but actively helps to regulate blood sugar. It's also antioxidant, antimicrobial, anti-inflammatory, and good for lung health.

What we know about the mechanism of migraines seems to imply that the problem involves rapid fluctuations of serotonin levels in the brain, leading to nitric oxide release--which either triggers pain due to blood volume, to oxidative stress, or both. This problem is compounded by methylation defects or a backup in the methylation cycle as well as (both related and unrelated) B12 levels.
