Ubos bark has a long history of use among the Indians and local people in the Amazon.* In South America this tree bark is considered a good anti-inflammatory and analgesic and used for inflamed and painful conditions like arthritis, rheumatism, and skin rashes.* For more information about ubos (Spondias mombin), please refer to the Database File for Ubos in the Tropical Plant Database. More information can also be found in the new Antimicrobial Guide. To see pictures of ubos, click here.

Traditional Uses:* as an anti-inflammatory for arthritis, muscle and joint injuries, etc.; as a pain-reliever for various types of internal and external pains; as an astringent and antiseptic wound healer for rashes, cuts, wounds, abrasions and other skin conditions; for rotoviral diarrhea and dysentery; for ovarian and uterine cancer

Ingredients: Ubos bark extracted in distilled water and ethanol. To prepare your own extract, follow the instructions provided on making tinctures at the Methods of Preparing Herbal Remedies page.

Suggested Use: Take 2 mls (about 1/2 teaspoon) 2 - 3 times daily or as needed. Can also be applied to the skin if desired.
Contraindications: Ubos bark is traditionally used as a contraceptive. While no animal or human studies support this traditional use, women seeking to become pregnant should probably avoid use of this plant.
Drug Interactions: None known

Antimicrobial Actions (bacteria, virus, fungi, candida):
Ubos bark has been reported with antibacterial actions in test tube studies against Pseudomonas aeruginosa and Bacillus cereus. It was also reported to inhibit human rotovirus by 82% in vitro which might explain its long standing use for diarrhea. In other in vitro testing researchers also reported that ubos bark has strong antifungal and anticandidal actions. The bark and the leaves of this tree have shown to have antibacterial and antifungal actions against some species that are stronger than the conventional drugs used to treat them.
