Thanks Gordof. I am in South East Asia, but actually looking for US testing places.

Agree with ozgirl and Perry. Proceed with caution and the simpler the better. Personally, I would not want any superfluous ingredients in a cream that I would not be comfortable dishing up to a 6 month old in a bowl. As a previous user of lanolin, I wouldn’t recommend anything else unless the user is looking for a vegan alternative (I had pet sheep as a child so partial to lanolin).

Have also used 3M masks:

@Belassi. This post is quite old, but if you are still working on it, it might be useful to consider quantifying components of the plant that have been correlated with the vasoactive effect eg acacetin and tilanin. See HPLC validation method attached (Hernández-Abreu et al). Also, one study noted that different subspecies of this plant have been shown in clinical studies to have different vasoactive effects, though they are used interchangeably in traditional medicine (see Ventura et al). 

I have been working on related problems and have also cross validated against soil surveys and previous land use patterns (eg industrial and agricultural use) to make better informed decisions about heavy metal and pesticide residue test selection for raw ingredients.  

Thank you for the forum @Perry. I am new to this field and find it highly informative and very interesting.
