Exploring the Potential of Damiana in Treating Diabetes : Traditional Uses and Scientific Evidence

1. Introduction—Use of Damiana in Treating Diabetes

   Damiana is a herb that has been traditionally used for its various health benefits, including treating diabetes. Diabetes is a chronic condition that develops when the body is unable to produce insulin or respond to it correctly, resulting in high levels of sugar in the blood. With the increasing prevalence of diabetes globally, there is a growing need to find new treatment options. The use of damiana for diabetes has been supported by traditional medicine, but there is limited scientific evidence to back up this claim. This article explores the potential use of damiana in treating diabetes, including its chemical composition and traditional uses. It is essential to consult a healthcare professional before starting any new treatment for diabetes.

   Overview of Diabetes and its Prevalence

   Diabetes is a chronic condition that develops when the body is not able to produce insulin or respond to it properly. This leads to a high level of sugar in the blood.

   Diabetes is of two main types:

   • Type 1 diabetes mellitus: It is an autoimmune condition in which the cells in the pancreas that produce insulin are destroyed by the immune system. This type of diabetes is usually known to develop in childhood or adolescence and the individual depends lifelong on insulin therapy.
   • Type 2 diabetes mellitus: In this type, the body gets resistant to the effects of insulin or is not able to produce insulin enough to maintain normal blood sugar levels. It is related to lifestyle factors, physical inactivity, and poor diet and is common in adults. However, it is also being increasingly diagnosed in children and adolescents as well.⁽¹⁾

   The prevalence of diabetes is observed to be increasing steadily over the past few decades. A study showed that in 2021 there were approximately 537 million adults with diabetes which were estimated to rise to 643 million by 2045.⁽²⁾

   Diabetes is known to occur in 90% of people, particularly in the lower and middle-income groups. It can lead to complications including heart disease, stroke, kidney failure, vision loss, and amputations. It is, therefore, important to manage it through lifestyle changes, medications, and regular monitoring.

   Importance of Finding New Treatment Options for Diabetes

   Diabetes is a growing health problem with an increasing prevalence in both developed and developing countries if the trend continues the current treatment option may not be sufficient to meet the growing demands.

   Finding new treatments for diabetes is therefore important. Other reasons include:

   • There are several treatment options and lifestyle interventions, but still, people struggle to achieve an adequate blood sugar level. Some even end up suffering from the related complications.
   • Some of the medications for diabetes cause unwanted side effects such as weight gain, gastrointestinal issues, and increased risk of hypoglycemia. By looking for new interventions the risk of these side effects can be reduced.
   • Every treatment does not work similarly for everyone. Something that may work for one person may not work for other. Having more options can help in providing a personalized treatment plan for every individual and increase the chances of a person benefitting from treatment.

   New treatment can be effective in improving the outcome of diabetes, reducing complications and economic burden, thereby improving the quality of life of a person.

2. The History of Damiana in Traditional Medicine

   Brief Overview of Damiana’s Traditional Uses

   Damiana is a low-growing plant that has yellow flowers and is native to the Subtropical climates of Southern Texas. It has been used as a herbal remedy for a long time. It is known to enhance sexual health and treat a vast array of symptoms from diabetes to anxiety.

   Some of the traditional uses of the damiana plant include:

   • Aphrodisiac: Damiana is used traditionally as an aphrodisiac.⁽³⁾ It is known to increase libido or sex drive and performance.
   • Digestive Aid: Damiana is also used traditionally for treating digestive issues including constipation, indigestion, and diarrhea. It can process the breakdown of sugar and fats in the digestive system and enhance nutrient absorption.
   • Anxiety and Depression: Damiana has also been in use traditionally as a remedy for anxiety and depression as it is believed to have a calming effect on the nervous system. It enhances energy and increases stamina and helps with lethargy and fatigue.
   • Respiratory Issue: It has been traditionally used as a bronchodilator to address issues such as asthma and bronchitis.
   • Menstrual Issues: Damiana has been in use traditionally also for menstrual and related issues which include cramps, irregular periods, and hot flashes.

   There are various traditional uses of damiana that have not been researched effectively. Also, it cannot be used as a substitute for medical treatment. Anyone planning to start it should speak with a healthcare professional to be aware of its effects.

   Evidence of Damiana’s Potential Benefits for Treating Diabetes in Traditional Medicine

   Along with various other uses, damiana has been traditionally in use as a remedy to control diabetes. However, limited scientific evidence back this purpose.

   There are more animal studies supporting the use of damiana for diabetes. A study done on rats found it to reduce oxidative stress on the kidney which occurs due to the mitochondrial stress in diabetes.⁽¹⁰⁾ However, it was not found to reduce hyperglycemia.

   Some studies show that damiana extract lowers blood sugar and improves insulin sensitivity but they were conducted mostly on animals.⁽⁴⁾ More research is needed to determine the optimal dose, duration of treatment, and safety of treating diabetes with damiana.

   Also, people with diabetes should always consult their doctor before going ahead with any type of treatment, even if it is a herbal or a natural treatment.

3. Chemical Composition of Damiana

   Overview of Active Compound Found in Damiana

   There are numerous active compounds present in the damiana plant. These include:

   • Flavonoids: There are flavonoids present in damiana including apigenin, luteolin, and quercetin, which are known for their antioxidant and anti-inflammatory properties.
   • Essential oils: Damiana contains essential oils in small amounts. These oils give plants an aromatic scent and have therapeutic effects as well.
   • Tannins: These are plant compounds that have antioxidant effects and reduce inflammation and promote wound healing.
   • Phenolic Compounds: Caffeic acid and chlorogenic compounds present in the damiana plant protect against oxidative stress.
   • Terpenes: There are a variety of terpenes present in damiana, which may help in reducing inflammation and promoting wound healing.
