Cassava (Manihot esculenta) is a plant sometimes used as an herbal remedy. The root of the plant is also used to make tapioca, a starch found in puddings and other foods. Taking cassava in dietary supplement form is said to offer a variety of health benefits, including enhanced fertility.

The root of the cassava plant contains significant amounts of several nutrients, including calcium and vitamin C. The plant's leaves, meanwhile, have been found to contain protein, carotene, and lysine.

Native to South America, cassava is one of the world's most widely consumed sources of carbohydrates.


In alternative medicine, cassava is used for a variety of conditions. Along with enhanced fertility, health claims for cassava include prevention of cancer and treatment of the following conditions:

  • Arthritis 
  • Conjunctivitis 
  • Diarrhea
  • Flu 
  • Headaches

Cassava also is purported to reduce inflammation and increase stamina.

In folk medicine, the roots of the cassava are applied directly to the skin (often in the form of a poultice) to promote the healing of wounds and sores.

Additionally, cassava root starch is sometimes used as an ingredient in vitamin C supplements.


The cassava plant can release cyanide (a potentially lethal substance) when consumed in whole form. Although proper preparation of cassava eliminates the presence of cyanide, incorrect preparation can lead to cyanide poisoning. Signs of cyanide poisoning include headache, agitation, and convulsions.

Due to a lack of research, little is known about the safety of longterm or regular use of dietary supplements containing cassava. 

Keep in mind that supplements haven't been tested for safety and dietary supplements are largely unregulated.

In some cases, the product may deliver doses that differ from the specified amount for each herb. In other cases, the product may be contaminated with other substances such as metals. 

Also, the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established. You can get further tips on using supplements safely here.


Although scientific support for the use of natural remedies in the treatment of infertility is fairly limited, some preliminary studies suggest that such herbs as maca may have fertility-boosting effects.

In addition, undergoing acupuncture may help improve fertility. While research on acupuncture and fertility has yielded mixed results, a 2011 report published in the Chinese Journal of Integrative Medicine found that "most of the existing studies suggest a positive effect of acupuncture in infertility treatment."

For help in preventing cancer, it's important to avoid smoking, limit your alcohol consumption, follow a balanced diet (including a high intake of fruits and vegetables, as well as food sources of antioxidants and healthy fats such as omega-3 fatty acids), maintain a healthy weight, exercise regularly, and limit your sun exposure.

There's also some evidence that certain natural substances may have cancer-fighting benefits. These substances include green tea, resveratrol, garlic, and turmeric. Additionally, some studies show that maintaining optimal levels of vitamin D may help protect against some forms of cancer.

Where to Find It

Often sold in capsule or powder form, cassava can be purchased in some natural-foods stores and stores specializing in herbal products. Dietary supplements containing cassava also are available for purchase online.

A Word From Verywell

Preliminary research suggests that linamarin (a compound found in cassava) may have cancer-fighting properties. In a 2002 study from the Journal of Gene Medicine, for example, tests on rats determined that linamarin may help destroy tumors.

However, clinical trials testing the anti-cancer effects of cassava are currently lacking, and overall research on the plant's potential health benefits is very limited.

Given the lack of supporting research behind cassava's purported health benefits, it cannot currently be recommended as a standard treatment for any condition. it should be noted that self-treating a condition with cassava and avoiding or delaying standard care may have serious health consequences.
