6 Fascinating Health Benefits Of Yucca: Dosage, Forms & Side Effects

Scientifically termed as Yucca filamentosa, yucca is a genus of perennial shrubs and trees belonging to the family Asparagaceae. Yucca is one amongst the 40 to 50 different species belonging to the family. The shrub is commonly mistaken with yuca or yuca root, which belongs to the genus Euphorbiaceae and has the common name of cassava [1] .

The fruits, seeds as well as the flowers of the plant, are used for consumption. Yucca is widely used for medicinal purposes and can be incorporated into your diet. Adam's needle is the most commonly used variety of yucca, due to the plethora of benefits it possesses [2] . The medicinal benefits of yucca can be attributed to the presence of saponins, resveratrol, and other phytonutrients present in the plant [3] . It can be used topically to treat skin conditions or wounds as well, and most commonly yucca is consumed in the form of a supplement.

Phytochemicals In Yucca

The plant contains various physiologically active phytochemicals such as steroidal saponins (commercially used as a saponin source). It is also a rich source of polyphenolics, including resveratrol and a number of other stilbenes such as yuccaols A, B, C, D and E [4] .

Health Benefits Of Yucca

The perennial shrub is asserted to possess the ability to stimulate circulation, improve digestion, reduce inflammation, and relieve pain. Various herbalists point out that yucca can be used in the treatment of high blood pressure, high cholesterol, migraine, diabetes, eczema, arthritis, stomach problems, skin infections, gall bladder and liver disorders [5] . Let's get to know more about the benefits provided by yucca and how it affects your body.

1. Manages arthritis pain

Various reports have pointed out that Native Americans have been using yucca for the treatment of arthritis pain and other symptoms [6] . The anti-inflammatory properties possessed by the plant help soothe and relieve the pain. Rich in compounds called phenols, yucca supplements not only reduce the inflammation but also neutralises the free radicals that cause harm to cells and tissues. Individuals suffering from osteoarthritis can exponentially benefit from yucca, thanks to its saponin and phytochemical content which help suppress the inflammatory responses in your body [7] .

2. Boots immunity

Rich in vitamin C and antioxidants, yucca is beneficial for your immune system. Along with that, it is also beneficial in improving the functioning of your immune system. It helps to protect your body against illnesses. The vitamin C content in the plant help stimulates the production of white blood cells that help the body to fight viruses and infection [8] . The antioxidants present in yucca protect your body from cell mutations and damage from free radicals.

3. Prevents heart disease

One of the major benefits of yucca is that it protects your heart by decreasing the imbalance between free radicals and antioxidants (oxidative stress) on the cardiovascular system. The free radicals can affect your heart health by accelerating various diseases such as heart diseases and cancer. By reducing the oxidative stress, yucca help reduce the excessive clumping of platelets; thereby reducing the overall risk of cardiac diseases [9] .

4. Reduces high cholesterol

Apart from improving your heart health, one other major health benefit of yucca is its ability in lowering high cholesterol levels. The plant-based chemicals steroidal saponins present in yucca upon consumption binds with the cholesterol and prevents its absorption in the intestines. This, in turn, helps reduce the cholesterol levels in the blood [10] .

5. Manages diabetes

According to a 2013 study, yucca is proven to be beneficial in regulating the metabolic disturbances in diabetic rats [11] . Although human studies are yet to be conducted, it was strongly asserted that yucca supplements are beneficial in boosting the health of diabetic individuals. It was found that yucca help regulates blood sugar levels by moderately reducing glucose levels.

6. Treats oxidative stress

A type of imbalance in our cells, oxidative stress can cause serious damage to our body. With time, oxidative stress can result in the development of conditions such as Parkinson's disease, Alzheimer's disease, heart failure, and inflammatory conditions. Studies support the claim that the antioxidants in yucca help protect your body from oxidative stress [12] .

Some of the other benefits of yucca supplements are that it is beneficial for your skin health. The photoprotective properties of the plant make it beneficial in acting as a protective shield against sun damage [13] . It is also used for the treatment for several other conditions, such as

  • skin diseases and infections,
  • sores and cuts,
  • dandruff,
  • sprains, and
  • balding.

Likewise, the folic acid present in yucca can help improve your eye health as well as your overall skin health [12] .


As of now, no exact amount has been set as a safe amount. So, consult your doctor and he or she can help you determine this on an individual basis [13] .
