Gustatory sensations were induced in a few cases among subjects with marked propagated sensation along channels (marked PSC), when their Spleen Channel was stimulated. When certain drugs with distinct taste were injected into the points of Spleen Channel such as the Sanyinjiao etc., a special sensation was evoked at these points and travelled along the course of this channel to the sublingual region, and following this, the subjects experienced a gustatory stimulation similar to that produced by oral administration of the same drug. This phenomenon coincides with the statement about the Spleen Channel in the Huangdi Neijing, ". . . it connects with the root of the tongue, and ends by ramifying in the sublingual region."
Sixteen experiments were performed double blindly on four marked PSC subjects by injecting solutions with different tastes, including 50% extract of Coptis Japonica, solution of vitamin B, isotonic saccharin sodium and distilled water at the Sanyinjiao or its neighbouring points on the Spleen Channel. All of the subjects experienced a taste of the injected solution and reported so, wherever the propagated sensation of the Spleen Channel had reached the sublingual region, although both experimenters and the subjects were ignorant of the solution used. Nine points were stimulated outside of the Spleen Channel as controls. The results showed that there was neither the PSC of the Spleen Channel, nor the appearance of taste of injected fluid in 8 cases. These experiments not only confirmed the fact that there was a kind of gustatory phenomenon appeared specifically on stimulating the Spleen Channel, but also provided an evidence clarifying the coincidence of the course of the propagating sensation and the traditional channel.
The gustatory sensitivity of one of the subjects was examined by a series of diluted quinine dihydrochloride solutions, indicating that the subject has very low gustatory threshold than normal persons. If distilled water, which is tasteless, was injected into the Sanyinjiao point, propagated sensation along the Spleen Channel occurred and reached the sublingual region, rendering gustatory threshold of the subject further lowered. It implies that when drugs were injected into the points of Spleen Channel, the special sensation thus evoked propagated along its course to the sublingual region, and the gustatory threshold of the subject was lowered to such a degree that although the drug acted upon the tongue through circulation was much smaller in dose than was injected, it could still be perceived at a lowered threshold. This might serve as a reasonable explanation of the gustatory phenomenon observed thus far.
