What You'll Learn
Australia's ginseng export potential
Australia has the potential to become an international supplier of ginseng, a medicinal herb with a rapidly expanding global market. Ginseng is a "cash crop" known as "green gold" that has attracted Australians for decades.
Despite the huge demand from China, Australia has not exported any locally grown ginseng to the country. In the 1980s, Fred Hosemans established Australia's first ginseng farm and envisioned exporting ginseng to China. However, his efforts did not succeed, and today only a handful of commercial ginseng growers remain in Australia.
The challenges of growing ginseng in Australia include invasions by native animals and birds, such as deer, wallabies, kangaroos, and wombats, which can damage the crops. Additionally, growing ginseng can be a steep learning curve, and growers need to share information and learn from their failures.
Nevertheless, Australia has the opportunity to cultivate, process, and market high-quality ginseng products to meet the global demand for medicinal herbs. With the right techniques and knowledge, Australia can potentially tap into the lucrative ginseng market and become a significant exporter of this valuable crop.

The challenges of growing ginseng in Australia
Despite the allure of growing ginseng in Australia, there are several challenges that growers face. Firstly, ginseng is native to Northeast Asia and North America, and some botanists believed that it could never prosper in Australia. This posed a significant hurdle for those interested in cultivating the crop.
One of the biggest challenges is the time it takes for ginseng to grow and reach maturity. Ginseng is a slow-growing plant, and it can take up to six years for the roots to reach their full potential in terms of size and medicinal properties. During this time, growers must be patient and careful not to disturb the roots, as premature harvesting can diminish the value of the crop.
In addition, protecting the crop from native animals and birds has been a constant challenge. Deer, wallabies, kangaroos, wombats, bush rats, lyre birds, possums, and parrots have been known to invade ginseng plantings. Bandicoots, in particular, are a major threat as they not only eat the above-ground plant but also burrow down to devour the roots. While growers have tried to protect their crops with rough wire fences and electronic deterrents, these methods have been only partially successful, and some have resorted to using wire igloos for better protection.
The steep learning curve associated with growing ginseng in Australia is another challenge. Growers must be willing to learn from their mistakes and share information with other ginseng cultivators. Attending regional growers' field days and staying informed about Australian growing techniques are crucial for success.
Lastly, the history of ginseng cultivation in Australia has been mixed, with more failures than success stories. Some people were initially drawn to the idea of a lucrative "retirement crop", but they soon gave up when they encountered difficulties. This has resulted in a decline in the number of commercial ginseng growers in the country.

The steep learning curve of growing ginseng
Growing ginseng in Australia comes with a steep learning curve. While the plant is native to northeast Asia and North America, Fred Hosemans, Australia's "godfather of ginseng", proved that it could also be grown in his home country. However, three decades after he established Australia's first ginseng farm, no locally grown ginseng has been exported to China, despite the huge demand.
Ginseng growers aiming to achieve simulated wild-grown ginseng normally plant seeds and let the plants fend for themselves. However, John and Jenny, who ran a ginseng farm for 15 years, went against this trend by using organic certified fertilisers to boost growth. They also had to address invasions by native Australian animals and birds, such as deer, wallabies, kangaroos, wombats, bush rats, lyre birds, possums, and parrots, who are fond of devouring the ginseng plant and root. To protect their crop, they used rough wire fences and electronic deterrents, which were only partially successful. They also had to deal with slugs and floods, which proved to be a major problem at their first farm.
Ginseng requires special conditions to flourish. It needs moist, well-drained soil with an optimum pH of 5.4, which can be adjusted with lime, dolomite, and gypsum. The soil varies throughout the farm, from loamy sand to heavier clays. The plants also need a canopy cover to maintain a minimum of 80% shade. Young plants, in particular, need to be well-watered while establishing.
Growing ginseng in Australia has been described as a "'coals-to-Newcastle' business idea that never quite took off. Despite the potential for high profits, there have been more failures than success stories. Those who have tried to grow ginseng in Australia have faced a steep learning curve and have had to learn from their mistakes through trial and error.

The lucrative nature of the crop
Ginseng has been known as "green gold" in Australia, where it has lured growers with the promise of high profits. The plant, known for its medicinal properties, is highly valued, especially in East Asia, where it has been used in traditional medicine for thousands of years.
In the 1980s, an article in an American magazine titled "Growing organic ginseng – $75,000 per acre" inspired Fred Hosemans, Australia's godfather of ginseng, to establish the country's first ginseng farm. Hosemans' vision was for Australia to export ginseng to China, which has a huge demand for the product. While Hosemans' efforts did generate interest from people looking for a lucrative "retirement crop", Australian-grown ginseng has never been exported to China.
Ginseng is a challenging crop to grow, and growing it can be a steep learning curve. It takes patience, as the roots need to be left in the ground for a long time to develop their medicinal properties and become more valuable. A half-hectare crop can net up to half a million dollars in Australia, while a single high-quality root can be worth thousands in China. However, the longer the root is left in the ground, the more susceptible it is to pests and diseases.
In addition to the potential for high profits, the growing global demand for medicinal herbs has encouraged Australia to develop a high-quality medicinal herb industry. With its recognition as a relatively high-cost producer, the country aims to focus on cultivating, processing, and marketing premium products.

The medicinal properties of ginseng
Ginseng is a medicinal plant that has been used for the treatment of various conditions and has been a part of traditional Chinese medicine for centuries. The root of Panax ginseng, or Korean/Asian ginseng, is a valuable and important folk medicine in East Asian countries, including China, Korea, and Japan. Known as "green gold", ginseng is a cash crop that has attracted many growers in Australia.
The major bioactive components of ginseng are ginsenosides, a group of saponins with dammarane triterpenoid structures. Ginsenosides are chemical components found in ginseng that are believed to be responsible for any clinical effects of the herb. Ginseng also contains gintonin, which works in conjunction with ginsenosides to provide health benefits. Ginseng has beneficial antioxidant and anti-inflammatory properties. A 2020 study found that ginsenosides may target pathways in the immune system that reduce inflammation. Another 2020 study found that various components in ginseng may influence the immune system and help prevent influenza, colds, and other respiratory infections.
Ginseng has been shown to have hypoglycemic and antidiabetic properties. Ginsenosides have been found to enhance glucose-stimulated insulin secretion and AMP-activated protein kinase (AMPK) in HIT-T15 cells, lowering plasma glucose levels. Ginsenosides may also reduce insulin resistance by regulating how the body breaks down lipids and blood sugar.
Ginseng has been linked to improved central nervous system (CNS) function, stress relief, and antioxidant activities. It may also help reduce some side effects of chemotherapy, such as fatigue. A 2018 review of 10 studies concluded that ginseng could significantly improve symptoms of chronic fatigue syndrome compared to a placebo. A 2021 review showed that taking American or Asian ginseng could decrease symptoms of cancer-related fatigue.
Additionally, ginseng has potent antibacterial, antifungal, and antiviral properties. A 2021 review found that ginseng could improve the self-reported ability of men to have intercourse, although it had little to no effect on erectile dysfunction or satisfaction compared to a placebo.
