Move over Viagra, there's a new "V" in town that may be equally effective for the treatment of male sexual dysfunction.
"Vuka-vuka" is an African plant that has been used traditionally in Malawi and Zimbabwe as a treatment for low sex drive and sexual dysfunction, the Council of Agriculture said yesterday at a press conference.
But Chen Yuan-wu (陳榮五), director-general of the council's Taichung district agricultural research and extension station, said that more research was necessary to determine vuka-vuka's effects before it could be sold as a treatment.
Vuka-vuka, which means "wake up, come alive" in the African language of Nguni, is a vine that is grown for its roots, Chen said, adding that the plant is high in nutritional value, containing vitamins A, D, E and K, as well as minerals such as zinc, iron and calcium.
"Vuka-vuka is known as the `African Viagra,'" said Chen, whose team have ground the root into powder and produced capsules.
What sets vuka-vuka apart from the "little blue pill" is its hormonal influence, Chen said.
"It has been documented that shortly after ingestion of vuka-vuka roots, one's face and head warm up as blood circulation increases. But beyond that, we have found that when fed to male rats, their male hormone level and sperm count also increases," he said, citing a study the station had completed.
"Our studies also indicate that there are no detectable negative effects to the function and structure of the rats' sexual organs, nor have we found vuka-vuka to be toxic," he said.
In addition to treating male sexual dysfunction, Chen's team believe the root may alleviate sciatic nerve pain and enlarged prostates, he said, adding that the effects were more prominent in subjects over 50 years old.
"Further research must be conducted before the plants can be marketed as medicine," Chen said. "The product is full of potential and we hope to work with research institutions to identify the active ingredients in the plant as well as their medical functions."
Chewing on a piece of vuka-vuka, Chen, who introduced the plant to Taiwan three years ago, said he had also come up with recipes combining the roots with traditional Taiwanese foods.
"Vuka-vuka makes a tasty chicken soup," Chen said.
"In the Taichung station we have named vuka-vuka `African ginseng.' It fits very nicely in soup. The plant has a very pleasant smell and was used as a spice and herb by Zulus in Africa as early as the 19th century," Chen said.
Considering that most countries issue more than five denominations of banknotes, the central bank has decided to redesign all five denominations, the bank said as it prepares for the first major overhaul of the banknotes in more than 24 years. Central bank Governor Yang Chin-lung (楊金龍) is expected to report to the Legislative Yuan today on the bank’s operations and the redesign’s progress. The bank in a report sent to the legislature ahead of today’s meeting said it had commissioned a survey on the public’s preferences.

The Centers for Disease Control (CDC) yesterday reported the first case of a new COVID-19 subvariant — BA.3.2 — in a 10-year-old Singaporean girl who had a fever upon arrival in Taiwan and tested positive for the disease. The girl left Taiwan on March 20 and the case did not have a direct impact on the local community, it said. The WHO added the BA.3.2 strain to its list of Variants Under Monitoring in December last year, but this was the first imported case of the COVID-19 variant in Taiwan, CDC Deputy Director-General Lin Ming-cheng (林明誠) said. The girl arrived in Taiwan on
South Korea is planning to revise its controversial electronic arrival card, a step Taiwanese officials said prompted them to hold off on planned retaliatory measures, a South Korean media report said yesterday. A Yonhap News Agency report said that the South Korean Ministry of Foreign Affairs is planning to remove the “previous departure place” and “next destination” fields from its e-arrival card system. The plan, reached after interagency consultations, is under review and aims to simplify entry procedures and align the electronic form with the paper version, a South Korean ministry official said. The fields — which appeared only on the electronic form
The Ministry of Foreign Affairs (MOFA) is suspending retaliation measures against South Korea that were set to take effect tomorrow, after Seoul said it is updating its e-arrival system, MOFA said today. The measures were to be a new round of retaliation after Taiwan on March 1 changed South Korea's designation on government-issued alien resident certificates held by South Korean nationals to "South Korea” from the "Republic of Korea," the country’s official name. The move came after months of protests to Seoul over its listing of Taiwan as "China (Taiwan)" in dropdown menus on its new online immigration entry system. MOFA last week
