Hi Melly, 
I just asked Marc and here's his answer.

Virtually everything that is safe to take orally can be used to sublingually 
“I/V” directly into the blood via the Sublingual Technique.  The only provisos 
we have seen so far is elemental copper solution, and only because it appears 
to stain teeth with frequent use.

Things folks have experimented with have been very diluted peroxide, French 
Green Clay and other clays, sodium bicarbonate (surprisingly noticeable for 
those with head fungal issues), Miracle II Neutralizer, Acidophilus, fulvic 
acid solution, and more.

Couple items that are notable too is the Bionaid silver solution (not colloidal 
silver, but silver ions bonded with ozone), and another product the same 
company makes called Micarox (and black mica solution).  One we are just trying 
now with notable effect too is getting Miracle II concentrated powder (little 
packet that normally makes gallon of Miracle II Neutralizer) and literally 
taking a few grains sublingually and holding for very long periods. 

Most of DMSO is converted once in the body to MSM.  DMSO has been tried too but 
for some folks there can be some sides (headache) beside the scent you note.  
Also, being a very strong solvent and “transporter”, anyone with amalgams 
should not use it.  MSM is perfectly safe, has many of the same properties 
(though OK with amalgams), occurs naturally in the body and our foods, the 
studies showing the pain relief aspects, and none of the side effects of DMSO.

Hope it's helpful. 
Be well,
Léna
