@gene, you are right, this is a good time to harvest tender, fresh leaves. I think the reason they encourage to shred them thin is to get the most nutrients out of them without boiling too long, just pour boiling water on them and let them sit for about 5 min... (Infusion). As we boil things they tend to lose some of their nutritional values.
@Greg, I have a potted fig, not sure what variety it is, i forgot, and the leaves do smell bad...I mean Skunk bad... this is a 3-4 foot tall branch that has about 6-8 leaves on it and regardless which one , they all smell awful (maybe it is VdB, as Suzi mentioned above, but, isn't VdB a Vista?)
@Costas, Caffein issue is not mentioned in any research I found on the net, but it would be very interesting to find out. What concerns to smelly leaves, I would just leave them alone, there are so many more varieties to take leaves from. Also, harvesting leaves shouldn't mean to strip the tree or the branch off of it's leaves entirely. Although , I have seen some YouTubes about Texan Everbearing being completely stripped off it's leaves in order to get plenty of sun to ripen the fruits at the end of the harvest season.
@Tom, although this smell resembles cat pee, it has NOTHING to do with cats or Skunks. LOL
@Pete, that recipe sounds very soothing, great for cold days... maybe even consumed chilled in hot seasons...I love Jujube. Ginger ir great for joint pains and arthritis, it is anti inflammatory. Cinnamon is good for diabetics and regulates body's glycemic index.
