Hi,
I looked through the paper. As tinnitus is not a real problem, but hearing loss, I looked for effects related to hearing loss and I have found something. Another paper from 2014. I states that Koread Red Ginseng has an otoprotective effect. The paper was only cited 4 times since then, so who knows whether this is bullshit or not but I think it is worth a try.
Tian, C., Kim, Y. J., Lim, H. J., Kim, Y. S., Park, H. Y., & Choung, Y. H. (2014). Red ginseng delays age-related hearing and vestibular dysfunction in C57BL/6 mice.
Experimental gerontology,
57, 224-232.
Here is the abstract. I have highlighted the interesting parts:
"Since Korean red ginseng (KRG) has been proven to protect against gentamicin-induced vestibular and hearing dysfunction, the effects of KRG on age-related inner ear disorder in C57BL/6 mice were investigated.
While age-related hearing loss was detected at the age of 6 months (32 kHz) and 9 months (16 kHz) in the control group, it was significantly delayed (p < 0.05) in the 150 mg/kg KRG-treated group. Vestibular dysfunction was observed in the tail-hanging and swimming tests, with significantly different severity scores and swimming times detected between the control and 150 mg/kg KRG-treated group at the age of 12 months (
p < 0.05).
Mice treated with 500 mg/kg KRG exhibited irritability and aggravated inner ear dysfunction. Histological observation supported the findings of hearing and vestibular function defects. In conclusion, C57BL/6 mice showed early-onset hearing loss and progressive vestibular dysfunction with aging, which were delayed by treatment with 150 mg/kg KRG. However, 500 mg/kg KRG treatment may induce aggressive behavior."
As I often have acute onset of hearing loss (for example when something was very loud or I sleep too less), which declines after 1 day, I will give it a try. But the dose of 150mg/kg per day is really much (12000mg per day for me). I think, I will start with a lower dose, maybe 4000mg per day.
Edit:
I have found a recommendation for human: "Accordingly, by referring FDA guidelines (
USFDA, 2005) for conversion of animal doses to human-equivalent doses (HEDs) (
Sharma and McNeill, 2009),
150 mg/kg KRG in the current study can be transferred to HEDs (assuming the human weight to be 60 kg) as 729 mg". This means, i will take around 1000mg/day.
