Lower bowel formula

I'm about to order the ingredients for Dr Christophers Lower Bowel Balance Formula from Mountain Rose Herbs.

Does it matter how many HU's are in the cayenne pepper? MRH only has 35,000HU's. Also, for lobelia, they don't specify what they have... It just says "Lobelia". Does that mean the whole plant then? Anyone know? They only seem to have raspberry leaf and not the powder as well.

I guess I need to look at Pacific Botanicals for the lobelia and the raspberry leaf and potentially a higher HU of cayenne?

Or... If anyone has any suggestions for a source for a premade LBB that would work too.
