<p>The best Ren Shen is from Shangdang, China. The Ren Shen from North Korea is second best. Some Ren Shen from North Korea tastes sweet, which isn&rsquo;t Ren Shen&rsquo;s original flavour. I once used sweet Ren Shen for the treatment of a hard glomus below the heart and it didn&rsquo;t improve. In Japan, Ren Shen is named Jiu Mo Nai Yi Fang. In Japanese culture, a bear&#39;s gall is also called Jiu Mo Nai Yi Fang, because both taste bitter. I once had young plants of Ren Shen from North Korea, grew them in Japan, and found that they all tasted bitter.</p>

<p>Ren Shen&rsquo;s original taste is bitter. Which is the same conclusion reached by Tong Jun and Lei Gong. My Ren Shen is grown in Japan and there&rsquo;s always a significant improvement to a hard glomus below the heart. Ren Shen should be cleaned and grated before use. The bitterness should not be removed.</p>
