Nature's farmacy: Coronavirus cure discovery? Cinchona - Fever Tree

by Alex Butova

As the world's health experts race to find a cure for the novel coronavirus, this drug have jumped to their attention - Chloroquine. It contains alkaloid Quinine, extracted from the bark of the Cinchona, or Fever Tree.
We receive many questions from our customers if we carry this plant. Although we do not offer it at the moment, we definitely can tell you more about this interesting medicinal plant!

If you like gin and tonic, you will be familiar with the bitter taste of the tonic which is provided by quinine. While it is now mainly used to add a flavor to our favorite tipple, the Cinchona tree bark once held a place as one of the most important drugs in history.
Cinchona was discovered in the 1630s as a treatment for malaria and, for 350 years, was the only effective cure known in Europe until synthetic replacements were developed in the 1940s. Malaria remains today one of the deadliest diseases known throughout the tropics, but up until the 20th century the disease was prevalent throughout Europe, including Britain.

The Cinchona tree is native to the Eastern slopes of the Andes with a range across Ecuador, Peru and Bolivia. Once the bark became an established medicine, particularly in the 18th and 19th centuries, demand started to outstrip supply. Threats of overharvesting and the desire to control the source of this precious bark drove various competing empires to source this plant for themselves. Understandably, the Spanish, who were in control of this area of South America, actively tried to prevent this, but failed to establish successful plantations themselves. A race to source and cultivate Cinchona ensued, and eventually both the Dutch, in Indonesia, and the British, in India, founded government controlled plantations for the mass production of quinine.

Chloroquine appears to have "broad-spectrum antiviral properties" and effects on immune response, and to be effective against severe acute respiratory syndrome... As the rest of the world, we are looking forward to the research results and hope the cure will be found soon!

Tu BiShvat - New Year for Trees

By Alex Butova

Tu BiShvat is the Israeli Arbor Day, and it is often referred to by that name in international media. Ecological organizations have adopted the holiday to further environmental-awareness programs. The modern practices and interpretations of Tu BiShvat often revolve around the earth and environment. This holiday is a celebration of nature and appreciation for creating the natural world. In Israel, Tu BiShvat is celebrated as an agricultural holiday. The 15th of Tu BiShvat was celebrated this year on February 10, 2020. This day marked the beginning of a new year for trees. This day marks the season in which the earliest-blooming trees emerge from their winter sleep and begin a new fruit-bearing cycle. Often the date of Tu BiShvat is used for determining the age of fruit baring trees and therefore establishes their birth dates. Therefore, Tu BiShvat is the "birthday" of trees!

The traditions and customs of Tu BiShvat vary, however, the most common include planting trees and gathering with family and friends for a meal. It is celebrated by eating fruit, particularly the kinds that praise the bounty of the Holy Land: grapes, figs, pomegranates, almonds, dates, olives and others. It reminds people that "a man is a tree of the field", and reflects on the lessons we can derive from the botanical analogue.

What pot is good for Medinilla?

Q: I just acquired a Medinilla plant. I have a cylindrical tall clay pot that I would like to repot this beauty into. Would like to know if a deep pot is good for this type of tropical plants even if the medium is lightweight with bark and perlite allowing adequate drainage. Would appreciate your advice.

A: Medinillas are very close to epiphytes, meaning they like high air humidity and very good soil drainage characteristics. Clay pots usually provide good air circulation, as long as they are not glazed. If you add a lot of soil conditioner into your mix, like orchid mix and perlite, the tall pot will provide a good drainage. Tall pot is also great for displaying the beautiful pendulous blooms!

Plastic pots work well too, as long as you provide a well-drained soil for the plant. If a nursery plastic pot is not pretty enough, you may place it in a fancy planter; however, make sure never let the pot sit in water, Medinillas do not like wet feet.
