Because red raspberry leaf is an herb rather than a drug, there are no "dosages" per se. However, the U.S. Pharmacopeial Convention (USP) suggests a guideline of between 4-8 grams of dried herb daily. Some herbalists and midwives recommend more. Although the percentages will change a little if you incorporate the optional add-ins, about 1-2 tablespoons of the tea recipe above roughly equals 4-8 grams.
