Evergreen tree up to 20 metres tall (65 ft). has star-shaped fruit, white blooms, and round lustrous foliage. Chest issues have traditionally been treated with soap bark. In the initial stages of bronchitis, its potent expectorant activity is helpful in the cure of the infection. The saponins in soap bark, like those in other medicinal plants, encourage the creation of an even more watery mucus in the airways, making it easier to cough up phlegm. However, soap bark shouldn’t be used to cure dry, grumpy coughs. Instead, it should be used to cure any condition that causes congested catarrh in the chest. Additionally used topically, soap bark can be found in dandruff shampoo formulas.
