    Celosia grows in my area (South Thailand) and I’ve collected the seeds from flowering plants. My question is : What is the exact decoction to use? Can I take the seed with no other herbs? I have mild hypertension. The seeds are so small that it took a long time to get a gram. Can I take less than the prescribed amount above and still notice an effect?
