Green Mental Health - Plant of the Day: Neem Tree "Azadirachta indica"

Spring came early to the Twin Cities this year.  We've already enjoyed highs up to the 70s (degF).  However, Mother Nature is reminding us that we *do* live in a northern, cooler latitude and in the past few days, our days have been much, much cooler.  Friday and yesterday, with temperatures hovering at and below freezing, Mother Nature sprinkled the Twin Cities with a beautiful light coating of tiny snow flakes.  Many of them melted depending on the surface temperature of where they landed.  Today, we have mostly sunny skies with forecasted highs around 40 degF.  As a southerner by birth and upbringing, I enjoy the warmth and high humidity that I experience in the beautiful Como Conservatory!  My volunteer time contributes greatly to my positive mental health.

As always, what a beautiful and inspiring day in the Conservatory!  I like to slowly walk through the Fern Room, the Palm Dome and the North Garden and test my knowledge on the scientific and common name of the various plants.  Not all are labeled, so I won't ever know every plant, but I will eventually know many of the plants.  I carry some of my training materials in my bag so I can check on some of the ones I either didn't know or forgot.  I love it when a visitor asks a question to test my knowledge.  Sometimes I don't know the answer and when I have to look it up, I learn something new!  I feel like I'm always learning something every time I volunteer.

The Plant of the Day is the Neem Tree - Azadirachta indica, also known as the Indian Lilac and the Nimtree.  The Neem tree is in the mahogony family Meliaceae.  The Neem tree is native to India and the Indian subcontinent including Nepal, Pakistan, Bangladesh and Sri Lanka.

The seed of the Neem Tree are used to create neem oil.  Neem oil is has been used for hundreds of years to control pests and diseases. Components of neem oil can be found in many modern products including toothpaste, cosmetics, soaps, and pet shampoos. Neem oil is a mixture of components. Azadirachtin is the most active component for repelling and killing pests and can be extracted from neem oil. The portion left over is called clarified hydrophobic neem oil.

Neem products are believed by many to exhibit properties of being antifungal, antidiabetic, antibacterial, antiviral, contraceptive and sedative.  Neem oil is also used for such processes as improving hair health, improving liver function and balancing blood sugar levels.

In India, dried neem leaves are placed in cupboards to prevent insects from eating clothes.   Neem leaves are also dried and burnt in various tropical regions to keep away mosquitoes.
