Mullein once again makes the list as an important herb to have in your herbal medicine chest. Mullein, also called lungwort, can be boiled to create a tea or respiratory tonic. Add honey to turn the tea into soothing cough syrup. Mullein is often used to reduce inflammation and may be used to help relieve symptoms of asthma or bronchitis. Be sure to consider mullein in your cough syrup mix.
Fortified milk is a great source of Lactobacillus. You should be cautious, however, as dairy may make phlegm thicker. You can also purchase probiotic supplements at most health food stores and drug stores. Each supplement manufacturer may have different daily recommended intakes. Probiotics are also added to some yogurt types and are present in miso soup and sourdough breads.
I have been suffering from this annoying dry cough for nearly 4 months. It may be because of post nasal drip. Had tried bronchial dilator, anti histamines and antibiotic too but cough comes back again. I regularly drink ginger tea and had tried honey as well but nothing helped. I also drink lots of water. I don’t cough all the time but when it comes it doesn’t go easily.

As I mentioned before the whole dandelion plant can be used. The root has many beneficial medicinal properties in the digestive system such as the stomach, liver, and pancreas. The dandelion root helps to increase digestive secretions and has also showed capabilities of stabilizing blood sugar levels. The leaf of the dandelion herb primarily acts on the kidneys helping with fluid clearance and even weight loss. Dandelion leaves are a common choice for those looking to lower blood pressure too. When combined with other herbs it works to effectively relieve skin problems such as acne, boils, and eczema.  
Known for its immune-boosting and disease-fighting benefits, this Chinese herb has several positive diabetes studies behind it. Re­searchers have found that ginseng slows carbohydrate absorption; increases cells’ ability to use glucose; and increases insulin secretion from the pancreas. A team from the University of Toronto has repeatedly demonstrated that ginseng capsules lower blood glucose 15 to 20 percent compared to placebo pills. These are the best superfoods for people with diabetes.

Teas are a great way to get the benefits of sage all you need to do is steep one teaspoon of sage in a cup of water for about 10 minutes. You can also make a pretty awesome sore throat reliever by combining sage and thyme. Take an ounce of both grind them, and cover them with 16 ounces of apple cider vinegar. Be sure to shake it periodically and let it sit for ten days before using.
