Both items though, are very different in nature and can be used at different times throughout your week.
Garlic has a heavy, almost meaty quality to it. It revitalizes and purifies the blood, and cleanses the digestive system, killing bacteria. But it is also very pungent and is better suited to be taken raw before bedtime.
A single garlic clove can be peeled and then chopped or crushes into "swallow-able" size and downed with water or tea. Be sure to drink enough water when you take raw garlic as raw garlic can also give a burning sensation and the water dilutes any harshness the rawness of the garlic brings with it. Water is also helpful for the quickening of the digestive system which always occurs after one has ingested raw garlic.
Some folks encourage the habit of taking one raw garlic clove every night, but not all. Raw garlic, fresh from the clove is a feisty substance and one needs to get to know how their particular body may react to it's active ingredients. Be prepared for any kind of effect which may or may not include a loosening of the stools and urgency to use the bathroom. Note that these effects may not always occur, once your body has become more accustomed to the presence of raw garlic.
And now for Ginger, yes it can also be taken raw. Raw ginger, after you have just peeled it, has a rather odd stringy juicy texture. Ginger has a more gentle and pleasant taste and aroma when compared to raw garlic, but it is no less feisty in terms of it's effects on the body. Ginger is a sweet success. You can peel it from it's knubby brown state, and then mash or chop it into bits, and swallow just about half of a teaspoon of some of the smaller sized pieces with water. Or you can just add some to boiling water and make a tea out of it.
Ginger has been known for centuries as a digestive aid. That's why our grandmas always endorsed the use of "ginger ale" to help calm down an upset stomach.
Well, that's about all for now. My blurt is done.
