Bitter melon is a fruit that can be found in many Asian grocery stores. As its name suggests, the fruit tastes very bitter. It's also available in liquid extract and capsule forms.
The fruit has a different warty looking external and an oblong shape. It is unfilled in cross-section, with a relatively thin layer of flesh immediate a central seed cavity filled with large flat seeds and pith. Seeds and pith appear white in unripe fruits, ripening to red; they are not intensely bitter and can be impassive before cooking. However, the pith will become sweet when the fruit is fully ripe, and the pith's color will turn red. The pith can be eaten uncooked in this state, but the flesh of the melon will be far too tough to be eaten anymore. Red and sweet bitter melon pith is a popular component in some special Southeast Asian style salad. The flesh is crunchy and watery in texture, similar to cucumber, chayote or green bell pepper. The skin is tender and edible. The fruit is most frequently eaten green. Although it can also be eaten when it has started to ripen and turn yellowish, it becomes bitterer as it ripens. The completely ripe fruit turns orange and mushy, is too bitter to eat, and splits into segments which curl back noticeably to expose seeds covered in bright red pulp.
Bitter melon comes in a variety of shapes and sizes. The typical Chinese phenotype is 20 to 30 cm long, oblong with bluntly tapering ends and pale green in color, with a gently undulating, warty surface. The bitter melon more typical of
Bitter Melon Medicinal uses
Though it has been claimed that bitter melon’s bitterness comes from quinine, no proof could be located supporting this claim. Bitter melon is traditionally regarded by Asians, as well as Panamanians and Colombians, as useful for preventing and treating malaria. Laboratory studies have confirmed that various species of bitter melon have anti-malarial activity, though human studies have not yet been published.

Laboratory tests suggest that compounds in bitter melon might be effective for treating HIV infection. As most compounds isolated from bitter melon that impact HIV have either been proteins or glycoproteins lectins), neither of which are well-absorbed, it is unlikely that oral intake of bitter melon will slow HIV in infected people. It is possible oral ingestion of bitter melon could offset negative effects of anti-HIV drugs, if a test tube study can be shown to be applicable to people. In one preliminary clinical trial, an enema form of a bitter melon extract showed some benefits in people infected with HIV (Zhang 1992). Clearly more research is necessary before this could be recommended.
The other realm showing the most promise related to bitter melon is as an immunomodulator. One clinical trial found very limited evidence that bitter melon might improve immune cell function in people with cancer, but this needs to be verified and amplified in other research. If proven correct this is another way bitter melon could help people infected with HIV.
