all joking aside, on my own I've been searching high and low for the same answer and have not yet happened upon it. I got a 16 oz bottle of this tincture recently along with a pound of leaves.
On recent CDs from MH, there is a section titled "website july", which contains the Olive leaf book.doc (183KB MS document that talks about the Morton book), the olive leaf Story.doc ( a 51KB MS document that talks more about Morton and mentions dosages using capsules and tea), and the olive leaf.doc (253KB document that looks like it may be the old j-counts on-line ad for the tincture product, or something from that era). None of these docs suggest a dosage for the tincture. MH gave me a copy of the Morton book - it's a great read, but as you may imagine it does not in anyway mention MH's proprietary tincture :)
I'm not done, there is still the new MH web site to explore, lot of paths to follow on that alone. Mean time, I decided to forge ahead without the answer, have been experimenting by taking a teaspoon dose first thing in the morning, have been doing this for about a week now. So far, everything still seems okay, no body parts have fallen off or stopped working, but this is still in the experimental stage ;) I really like the taste of this tincture. For long-term purposes, it is probably a bit rich for my means. Even at 1 teaspoon per day (what I'm guessing is a very conservative daily amount to take), this will only last a month or so. I may soon advance to making tea from the pound of leaves I got and after that I may even experiment with making my own capsules. Most of the dose info I've found seems to be based on capsules.
