Er Long Zuo Ci Wan (Er Long Zuo Ci Pian, 耳聋左慈丸) is a Chinese herbal medicine specially formulated for tinnitus and deafness. It is derived from Liu Wei Di Huang Wan, a well known Chinese herbal medicine that nourishes Yin of the Yin-Yang energy. Er Long Zuo Ci Wan is commonly used by Chinese doctors for tinnitus and hearing loss due to kidney Yin insufficiency.

What does it do?
In Traditional Chinese Medicine (TCM), the kidney is fundamental to all organs and generate Yin and Yang. The function of the kidney is believed to reflect in the ears. When the kidney gets weaker, tinnitus is often observed along with other signs such as low back pain (weakness and soreness) and dizziness. It may also come with hearing loss. The tinnitus is usually felt as a buzzing sound, low but persistent, day and night (may get worse in the night time). If the kidney deficiency is on the Yin energy side, the symptoms may also include sweating. This type of tinnitus tend to occur in the elderly people, or those with excessive sexuality. Er Long Zuo Ci Wan nourishes kidney Yin and is suitable for kidney Yin deficient tinnitus. It is however not suitable for any tinnitus with an abrupt onset. Please note these herbal remedies do not apply to tinnitus that occurs suddenly.

Er Long Zuo Ci Wan has been indicated in China Pharmacopoeia¹ for nourishing the kidney for subduing the hyperactivity of liver-yang. The herbal formula is used for tinnitus, deafness, dizziness, and blurring of vision caused by deficiency of both liver Yin and kidney Yin.^†.
