Well, since you already have the samento, you can also look at Buhner's site to help you with dosing. Usually we recommend starting off with just ONE drop in a very small glass (like a shot glass) of water:
www.buhnerhealinglyme.com/Once you can tolerate one drop, take one drop in the am and one drop in the pm. Once you can tolerate that dose, take one drop early am, one drop midday and one drop pm. Once you can tolerate those dosages, then work on raising each of them individually. Take 2 drops in the am, 1 midday, 1 pm. Once that's tolerated, take 2 drops in the am, 2 drops midday, and 1 drop pm - and so on.
Many people find they can raise their doses quite quickly this way, yet can stop raising the dose as soon as they find the level at which they start their herxing.
If you wish to follow Buhner's protocol, then you add in Japanese Knotweed in the same manner. And once you have that added in you can add in the Eleuthero - which is the core protocol for Buhner. There are other tinctures that you can add in depending on what you are dealing with, so take a good look around his site. There is a ton of information there.
