Potential medicinal uses and adverse effects
Though long-used in traditional medicine, there is little evidence that clove oil containing eugenol is effective for toothache pain or other types of pain, although one review reported efficacy of eugenol combined with zinc oxide as an analgesic for alveolar osteitis. Studies to determine its effectiveness for fever reduction, as a mosquito repellent, and to prevent premature ejaculation have been inconclusive. It remains unproven whether blood sugar levels are reduced by cloves or clove oil. Use of clove for any medicinal purpose has not been approved by the US Food and Drug Administration, and its use may cause adverse effects if taken orally by people with liver disease, blood clotting and immune system disorders, or food allergies.
Traditional medicinal uses
Cloves are used in Indian Ayurvedic medicine, Chinese medicine, and western herbalism and dentistry where the essential oil is used as an anodyne (painkiller) for dental emergencies and various other disorders. The essential oil is used in aromatherapy.

The first clearly dated archeological find of a clove is substantially later than the written evidence, with two examples found at a trading port in Sri Lanka, dated to around 900-1100 CE. An earlier reported find, in Syria, dated to around 1700 BCE, is no longer believed to be a clove.

Until modern times, cloves grew only on a few islands in the Moluccas (historically called the Spice Islands), including Bacan, Makian, Moti, Ternate, and Tidore. In fact, the clove tree that experts believe is the oldest in the world, named Afo, is on Ternate. The tree is between 350 and 400 years old. Tourists are told that seedlings from this very tree were stolen by a Frenchman named Pierre Poivre in 1770, transferred to the Isle de France (Mauritius), and then later to Zanzibar, which was once the world's largest producer of cloves.
Until cloves were grown outside of the Maluku Islands, they were traded like oil, with an enforced limit on exportation. As the Dutch East India Company consolidated its control of the spice trade in the 17th century, they sought to gain a monopoly in cloves as they had in nutmeg. However, "unlike nutmeg and mace, which were limited to the minute Bandas, clove trees grew all over the Moluccas, and the trade in cloves was way beyond the limited policing powers of the corporation."
The compound eugenol is responsible for most of the characteristic aroma of cloves
Eugenol composes 72–90% of the essential oil extracted from cloves and is the compound most responsible for clove aroma. 100% extraction occurs at 80 minutes in pressurized water of 125 °C. Ultrasound-assisted and microwave-assisted extraction methods provide more rapid extraction rates with lower energy costs.
Other important essential oil constituents of clove oil include acetyl eugenol, beta-caryophyllene and vanillin, crategolic acid, tannins such as bicornin, gallotannic acid, methyl salicylate (painkiller), the flavonoids eugenin, kaempferol, rhamnetin, and eugenitin, triterpenoids such as oleanolic acid, stigmasterol, and campesterol and several sesquiterpenes.
Eugenol is toxic in relatively small quantities; for example, a dose of 5–10 ml has been reported as being a near fatal dose for a two-year-old child.

Typically, okra is used as a thickening agent in soups like gumbo because of its ooey-gooey texture, but it can double as a nutritional powerhouse filled with vitamins, minerals, and other nutrients that provide an array of health benefits from treating diabetes to preventing kidney disease. A single cup of raw okra has a little over 30 calories, about 3 grams of dietary fiber, 2 grams of protein, 7.6 grams carbohydrates, 0.1 grams of fat, 21 milligrams of vitamin C, around 88 micrograms of folate, and 57 milligrams of magnesium. This makes okra a nutrition hero and a very available food when it comes to our health.
In one study, researchers gave three grams of cardamom powder a day to 20 adults who were newly diagnosed with high blood pressure. After 12 weeks, blood pressure levels had significantly decreased to the normal range (3Trusted Source). The promising results of this study may be related to the high levels of antioxidants in cardamom. In fact, the participants’ antioxidant status had increased by 90% by the end of the study. Antioxidants have been linked to lower blood pressure (3Trusted Source, 4Trusted Source). Researchers also suspect that the spice may lower blood pressure due to its diuretic effect, meaning it can promote urination to remove water that builds up in your body, for example around your heart.
