I think the Balsam (Impatiens balsamina Linn.) is a must-have plant in any garden.
This plant is locally known as Kamantigi or Kalamatigi. Its has pretty English common names though, such as Rose Balsam, Jewelweed and Touch-me-not. However, the name Balsam gives you an idea that this plant it is a medicinal as well as an ornamental.
The Balsam flowers bloom in pink, white, red and lavender and variegated petals.
Though it is widely cultivated for ornamental purposes throughout the Philippines, I planted the Kamantigi for its medicinal purpose.
Whenever I have cuts or bruises, I would often get me some of the Kamantigi flowers, crush them and apply the extract directly on the affected parts of the body. Its anti-inflammatory properties alleviate any pain or swelling in my skin.
This plant is listed as one of the medicinal herbs in the Philippines. http://www.stuartxchange.org/Kamantigi.html
