Diabetes Herbs

Diabetes mellitus is a metabolic disorder of the endocrine system. Metabolism is the process of making energy from the food you eat. A metabolic disease develops when there is any defect in this process. When this disorder develops, you might have an excess of some substances or a shortage of others that you need to stay healthy. 

The metabolic disorder develops when the liver or pancreas does not function normally, like in the case of Diabetes.

Diabetes drugs are developed based on the medicinal herbs

Many conventional medicines have been derived and formed similar to a molecule in traditional medicinal plants. 

For example, Metformin, considered to be an efficient oral glucose-lowering agent, is developed based on the plant Galega officinalis used to treat diabetes. Scientists form a molecule and its action similar to that of the natural herbal molecule. However, the human cannot match the millions of years of slow evaluation. So, natural made is always safe compared to human-made things. Also, nature gifted us with this healing molecule packed with a perfect combination of other natural ingredients to make it work at its best. However, humans try to isolate this molecule as a chemical, so its healing effect reduced additionally with numerous side effects.

Diabetes drugs develop resistance & side effects 

Synthetic oral anti-diabetic agents have certain drawbacks, such as building resistance in the long run, adverse effects, and lack of action in a large segment of diabetes patients. 

Approximately 44% of diabetes patients develop resistance to sulfonylurea treatment within six years.

Additionally, these oral agents are associated with adverse effects such as bloating, flatulence, diarrhea, and abdominal discomfort. Some anti-diabetic agents can cause toxic effects; for example, thiazolidinedione may cause liver toxicity, and sulfonylureas may worsen heart disease, cause hypoglycemia, and increase body weight. 

Many diabetes patients turn towards herbal treatment

The National Health Interview Survey found 22 % of diabetes used herbal remedies!

Plants provide hypoglycemic property and traditionally used to prevent or treat diabetes. These plants additionally have the benefits of delaying diabetic complications, exhibits antioxidant activity, and lower blood pressure & cholesterol.

Cumin seed, cinnamon stick, and ginseng root as tea separately or in combination for better blood sugar effects. Guava and mango leaf tea can be taken daily individually or as a combination. Change or modify the tea recipe for every month. You can consume other herbs as directed in a cyclic rotation.

You can take diabetes herbs along with your drugs; however, you should be more vigilant because you may end up in low blood sugar (Hypo). Also, some herbs may interfere with your drug, and it might increase or decrease its effectiveness or worsen the side effects. 

Co-administration of conventional drug and herbal medicine may cause potential interactions that lead to adverse events. So, get a doctor’s consent before starting herbal treatment.

So, you need to do enough research by taking into account the health problems you have and the drug you are on before start taking herbs.

Are herbs available in the market safe to consume?

There is no single definite answer to this because it depends upon the supplier. So, you should be more vigilant and analyze the supplier by going through reviews by fellow users (also, you should be cautious whether the reviews are genuine).  

It is always preferable to have herbs by taking decoction by boiling it in low flame for an extended period because this helps to destroy any microorganism in the herbs while processing.

Are there any side effects of diabetes herbs?

Generally, most of the herbs suggested here are safe to use. However, diabetes herbs contain natural chemicals that might interfere with your medications and may cause untoward symptoms. Also, taking too much of certain herbs may cause adverse effects. For example, taking a large quantity of bitter gourd juice daily in an empty stomach can upset your stomach. However, if you take it as per the recommended amount (100ml) and frequency (2 to 3 times a week), this will not cause any side effects.

So, take herbs after doing enough research and practice limits in quantity and frequency. Also, cyclically rotate the herb used for every 30 days; that is, a set of herbs for a month, next set for next month, and so on and you can repeat the same set in cyclic manner.
