Too late to help now, but Ashwagandha doesn't do anything all that profound that it would affect you that much, unless you overdosed, in case you should have seen a physician. Herbs contain two kinds of chemcials -- fat soluble, and water soluble. The water soluble leave the body quickly, the fat soluble slowly, as they're stored in fatty tissue. As to duration, herbs are food, and are digested as such, so the duration of their presence in the body has to do with your metabolism, digestive efficiency, etc. We're all a bit different this way. But because herbs are food, they are usually dosed two to three times a day to keep them in the system -- that should tell you how long most of the constituents last.
Well i took allot. Im rely just looking for the half life or something because there is not a single piece of info on the interne stating how long this herb keeps working.
You don't say how many mg. you have taken and when was the last time you took it! That said this is the best I can tell you as each person is different!
As an herbal dietary supplement, take one ashwagandha capsule a FEW TIMES PER WEEK. This herb, in some individuals, may cause drowsiness or sleepiness. Others who are restless or anxious may feel relaxation but no drowsiness. I suggest you avoid a high dose in the evening since sometimes it has a stimulatory effect before leading to sedation. For those who are tense and anxious, and hyper alert, ashwagandha can be taken during the day, for others, it is best taken in the evening. Most herbs are better absorbed on an empty stomach. There are no dietary restrictions with its use.
Have there been reviews to see which ashwagandha supplement is best?
Not that I am aware of. However, different processing procedures and different extraction procedures are likely to make the different products produce slightly or moderately different effects in terms of reduction of anxiety or influence on mood and sedation.
I prefer taking breaks from the use of herbs, that is just my personal viewpoint since I tend to err on the side of caution.
