You asked what your current tea (herbal infusion) is doing to you and it seems that no one answered that, so let me give you some advice as an herbalist.
Your first ingredient Tarragon is a great herb for healthy and great tasting chicken and other food, but I haven't found very much detailed research on it's medicinal properties and effects on the human body, other than the obvious fact that it's edible.
Rosemary, also being a great herb for cooking, this herb does contain viable medicinal qualities when prepared correctly in herbal remedies. Rosemary is a great source of antioxidants which help elinimate harmful free radicals from your body. It is a hepatoproective which means that it stimulates normal functioning of your liver while also acting to protect the liver from harm and damage caused from increased toxicity in everyday consumption of food and beverages with synthetic chemicals and other harmful additives. Rosemary is also effective in treating poor blood circulation, in which case Rosemary is specifically good for memory and neurological problems because it helps increase oxygen flow to the brain. Other uses include as an upper intestine antispasmodic, enhances appetite and digestion, respiratory and sinus congestion, high blood pressure etc.
Marjoram is another common culinary herb and great for cooking but I am unfamiliar with any significant medicinal qualities that it may possess however I see no objection for using the herb in a herbal preparation.
Basil again is another culinary herb used in cooking fine meals, however this herb does have medicinal properties, unbeknownst to me until recently. Basil is a great anti-inflammatory which helps reduce inflammation and swelling. It apparently has many other uses but I am still researching it's medicinal properties and effects within herbal medicine. However here is a great article I found that can further assist you on the research: http://www.offthegridnews.com/2011/04/21/medicinal-uses-and-health-benefits-of-basil/
Cinnamon is one of my favorite herbs not only for it's great taste but also for it's very valuable medicinal properties, especially to myself. Cinnamon is an aromatic and gentle herbs that is tonifying to the entire nervous and circulatory system. It is also a gentle stimulant with a small astringent influence. Current research shows and I find it beneficial and exciting that  several polyphenolic polymer compounds found within Cinnamon bark stimulate and enhance the action and production of insulin; and it helps balance blood sugar (glucose) levels as well as the body fat metabolism.

Cloves are a very potent and aromatic herb and while it does contain some beneficial medicinal uses, I air on the side of caution due to current research that proves Cloves contain hepatoxic properties that are harmful to the liver if taken in large doses or prolonged use over time. From that note Cloves possess antiviral and antibacterial properties that help aid the body to fight of an infection. Cloves are also useful for quick relief of nausea, it is also an anti parasitic which means it helps remove parasite from the body. In addition it is a mild carminative and can help relive gas and bloating.
Thyme, another culinary herb, is an aromatic, gentle carminative that helps relive gastric distress, flatulence, diarrhea, and gastrointestinal spasms. In addition it is also a respiratory system stimulant and protective which helps for bronchial distress, asthmatic, and irritated or constricted air pathways.
Ginger is one of greatest herbs in my opinion. Ginger has a wide range of uses and is most commonly used for stomach and gastrointestinal irritation and distress. It is a gentle sedative that helps calm anxiety. It is great for the heart and circulatory system and is also a metabolic stimulant that helps maintain and balance appetite. It is also an antioxidant and anti-inflammatory.
As you can see from the medicinal action that these herbs have that are quite beneficial, although I do not know your formulary or measurements I suggest you look into balancing the amount of herbs you use and ratio them appropriately as to maintain an effective herbal infusion and preparation. I agree that you should research carefully and patiently any herb and their interactions before you use them, as well as mixing ratios when combining two or more herbs together. Again I air on the side of caution when using Cloves and recommend that you don't use more than 1/8 of a teaspoon per 8 oz. cup of tea.
I hope this helps with your question, at least the physical medicinal portion of what this herbal combination is doing to you.
