Black mashua is a tuber valued for its medicinal properties. We’ll inform you all about its advantages and uses here.

The black mashua, whose scientific name is Tropaeolum tuberosum, is a tuber native to the highlands of the Andean region, which incorporates countries corresponding to Peru, Bolivia, Ecuador, and Colombia.

Meanwhile, the book Lost crops of the Incas: little-known plants of the Andes with promise for worldwide cultivation (cited by Wikipedia) states that every 100 grams of dried specimens of those tubers provide the next:

  • Calories: 371
  • Total carbohydrates: 78.6 grams
  • Protein: 11.4 grams
  • Fiber: 5.7 grams
  • Ashes: 5.7 grams

  • Calcium: 50 milligrams
  • Phosphorus: 300 milligrams
  • Iron: 8.6 milligrams
  • Beta-carotene: 214 micrograms
  • Thiamine: 0.43 milligrams
  • Riboflavin: 0.57 milligrams
  • Niacin: 4.3 milligrams
  • Ascorbic acid (vitamin C): 476 milligrams

The magazine Engineering Research highlights that black mashua is one in every of the tubers with the very best vitamin C content. It also needs to be noted that the Tropaeolum tuberosum species is an abundant source of antioxidant substances.

A study shared through the International Journal of Food Science lists this food as “a precious natural source of phenols and anthocyanins with high antioxidant activity”. The Peru website adds that mashua provides between 9000 and 10 000 units of antioxidants, which explains its ability to contribute to cell renewal and health care.

Possible advantages of black mashua

As a result of its interesting dietary value, the consumption of black mashua is related to some health advantages. Nonetheless, it needs to be noted that the evidence supporting its effects continues to be limited. What is thought thus far?

Compounds corresponding to flavonoids and polyphenols could be behind these effects.

In other research, reported within the journal Phytochemistrytwo alkaloids isolated from the black tubers of Tropaeolum tuberosum were found to have the potential to kill cancer cells in lung, bladder, kidney and prostate cancer. Cytotoxic activity was also observed.

Meanwhile, an in vitro study shared by Biomedicine and Pharmacotherapy concluded that ethanolic extracts of black mashua, moringa, and custard apple have inhibitory properties on colorectal cancer cell lines. And while further studies are needed, they’re believed to be future candidates for improved therapy against this way of cancer.

Natural diuretic

As a folk treatment, black mashua is used to advertise the relief of fluid retention. Anecdotal data suggest that extracts of the plant increase diuresis (urine secretion), which in turn promotes de-inflammation.

Nonetheless, there are usually not enough pharmacological studies to verify these properties.

Antihistamine potential

This tuber is utilized in traditional medicine as a treatment to assuage allergy symptoms. Although there are not any concrete studies on these properties, it’s believed to be resulting from its high flavonoid content.

As stated in a study reported in Allergology International, adequate intake of flavonoids serves as a preventive strategy against allergic diseases. It has been observed that these substances help inhibit the discharge of histamine.
