Sorry, J -- I should think clearer before posting. Yes, vasoconstrictors raise blood pressure. I was kind of freaked by TommyD's warning: "The various natural sources of LSA may contain other related substances in the ergot family, and some of these are not so friendly. Many have a severe vasoconstrictive effect - narrowing the blood vessels and reducing blood flow, sometimes dangerously - that can cause serious, even fatal medical consequences." I jumped to overworrying and getting it wrong. Thank you for correcting me. That warning's still scary, though!
