    On the 3rd day I drank cassia tea, about 2 tsp with 1 1/2 pints of water, boiled 10 minutes. Mid-afternoon, I felt so drowsy,I fell asleep in the sofa, must have been at least 2 hours. I know I have not had good sleep in the past, although the other day, I had a good night’s rest – 7 hours of sleep. Perhaps my body was needing all that rest I missed in a long time. Urination felt good, more of it coming out and there is a sense of well being. I know my body, so I meticulously watch how new medication, tea, or food affects me. I do take cassia tea in moderation to see which range or dosage brings in better benefits to my body. The first time I smelled it at the store (although the cover is well placed- you have to pull the plastic tab to open it), I inhaled some part of it and the result was a subtle, brief relief in my breathing. I did not pull out the plastic tab until I brought it home to boil 2 tsp of the seeds to make tea. I believe this tea is truly beneficial for weight loss, cleansing the kidney and liver of lead, and eye care. About 10 years ago, I was diagnosed with asthma, but this tea does not adversely affect my breathing. I had been off asthma medication since I felt it was like something I cannot live without – becoming fully dependent on it. To help avoid any breathing difficulty, I avoid environmental factors that could bring in any breathing difficulty, such as extreme heat, strong wind that tend to bring in pollen, dust, etc. along with it, and I do work out at least 4 times a week. I think I will try the cassia pillow, too. Just be careful not to take cassia tea in excess because it tends to relax your body way too much, you would want to lay down for a long time. This has been my experience. Recommend cassia seed dosage in this article is, from 9-15 grams in decoction. The serving size of 1 tsp cassia seeds is equivalent to 5 grams. So from this, you can do your math as to how much to tea to drink.

    Continuing my journal regarding drinking cassia tea – my 9th day drinking the tea. Still experiencing the good benefits of drinking cassia tea to the well being of my body. The only thing I had to do was limit my drinking the amount of cassia tea. For several days, I had been drinking 8 small tea cups of tea a day, extending it from morning until evenings. I noticed sore muscles during physical exercise ( zumba, body works). So, I stopped drinking the tea for a day, then I continued again at 2 tiny tea cups per day. I noticed reduced sore muscles during exercise. Moderation in drinking this tea is important. This is probably why they recommend consulting the doctor when taking it. Another good experience with this tea is it has improved the quality of my sleep at night. I felt more relaxed and slept much earlier than usual. I used to go to bed at 2:00 a.m. or 3:00 a.m, and sometimes at 6:00 a.m. Now, I am able to go to sleep around 11:00 p.m., waking up at 6:45 a.m. I think it is best to drink this tea after evening meal. This way, the tea’s relaxing effect comes at a time you’re ready to fall asleep and it does help you relax to fall asleep. It also depends on how your body reacts to what you take in. If something I take would give an adverse effect (not feeling good, or stomach ache), I stop taking it. Cassia seed tea does not give me such problem.
