It is safe when the herbs blended "play well" together. If you will notice - some of the weight amounts are very small - this is because some herbs need less by volume than others for effectiveness. It all depends on the quality of the herbs being used.
I guess it is a trust issue to know that all ingredients are in the products. After all - it is only my word that they are there.
We have been doing this for a long long time. We have never advertised as all of our customers are word of mouth and hear about us from other customers - and this has happened since the early 1930's.
We don't use fillers or sawdust or sand in our products - you get the real deal. That is why I use the clear capsules - so a person can see what they are getting. We also make each product here from the herbs that I personally take care of - humidity, age, moisture content, temperature, light exposure, etc. ALL make a huge difference in the quality of the end products.
I can't and won't trust this to a mass capsule making factory. It is all done here - where I know it is done right.
