Hepatitis ✪✪✪✪✪
The effect of Desmodium has been evaluated in small clinical studies (between 10 and 50 patients) conducted on hepatitis B and C cases, using 10 g of dry plant. The results show normalization of aminotransferase levels (ASAT/ALAT transaminases) for 96% of patients, bilirubin in 76% of them, disappearance of myalgias for all patients, as well as disappearance of jaundice (97%) after 45 days of treatment. Finally, it was noted that Desmodium gives good results on hepatitis A, B, and C when administered during the viral invasion phase accompanied by the clear symptomatology of infectious jaundice (yellowing, asthenia) and a change in biological parameters like transaminases or bilirubin. Desmodium can be indicated not only in cases of viral hepatitis but also for preventing hepatic alteration induced by chemotherapy or hepatotoxic substances.

Allergic Rhinitis ✪✪✪✪✪
The antiallergic action of Desmodium is highlighted in traditional medicines. Desmodium is used in case of recognized allergic condition (dermatological hypersensitivity, runny nose, allergic rhinitis, etc.). In the Indian Ocean and Africa, Desmodium leaf powder is used to soothe coughs and treat asthma.
Posologie
Detoxification ✪✪✪✪✪
The high concentration of polyphenols in the leaves of Desmodium, as well as triterpenoid saponosides, make it a beneficial supplement for protecting the liver against daily natural attacks (oxidation, toxicity, damage, etc.). Traditional medicine recommends it as part of an overall approach to liver support during seasonal detoxes.

Asthma ✪✪✪✪✪
The antiasthmatic action of Desmodium is highlighted in traditional medicine. Desmodium is used in cases of recognized asthmatic condition. The leaf and stem powder of Desmodium is also traditionally used to soothe coughs and treat asthma. It has been demonstrated that Desmodium inhibits the action of histamine on bronchial smooth muscles and decreases constriction (relaxing effect) of the airways and lung tissues. Under these conditions, its antihistamine effect will act on the allergic terrain of asthma, and its bronchodilator effect will help to effectively fight against bronchial asthma attacks.

Allergies ✪✪✪✪✪
The antiallergic action of Desmodium is highlighted in traditional medicine. Desmodium is used in cases of recognized allergic conditions (dermatological hypersensitivity, discharges, allergic rhinitis, etc.). Desmodium adscendens, used by herbalists in Ghana for asthma treatment, is anti-anaphylactic in vitro. Given that the plant extract is administered orally, in vivo studies on its anti-anaphylactic properties were conducted using guinea pigs. Aqueous and ethanolic extracts of D. adscendens, when taken orally, reduce anaphylactic and histamine-induced contractions and decrease the release of smooth muscle-stimulating substances from lung tissue.

Hepatic steatosis ✪✪✪✪✪
The leaves, or even the whole plant, are frequently used in cases of liver problems and hepatitis in Peru, Brazil, and Cameroon. Traditionally, about 8 to 10 g - depending on the patient's weight - of dried aerial parts, harvested when the plant is not flowering, are boiled for about 15 minutes in a large volume of water (1 to 1.5 l). The filtrate is then consumed throughout the day. The duration of the treatment in this case depends on the prior jaundice and is administered until the complete disappearance of symptoms (in 7 to 15 days), and biological signs (in 4 to 6 weeks).
Posologie
Chemotherapy ✪✪✪✪✪
A small-scale clinical study has highlighted a beneficial effect of Desmodium on liver function in patients suffering from different types of cancer and treated simultaneously with chemotherapy. The results show a significant positive effect on phosphatases, nausea, and transaminases. Desmodium appears promising in supporting chemotherapy protocols, but further studies are needed to confirm these results.

Posologie
Properties
Hepatoprotective
The hepatoprotective effect of Desmodium against hepatotoxic compounds seems to be related to its content of triterpenoid saponins. Indeed, an in vivo study (on animals) showed that soyasaponins I and III, dehydrosoyasapogenin I, and soyasapogenol E protect liver cells from damage induced by hepatotoxic substances such as carbon tetrachloride (CCl4, which causes an increase in transaminases). As a result, treatment with Desmodium led to the normalization of liver transaminase levels (mainly alanine aminotransferase and aspartate aminotransferase) in this study.
Usages associés
Antiallergic
Studies using aqueous and ethanolic extracts of Desmodium have been used in vivo. These extracts counteract contractions induced by histamine, reduce the amount of antigenic substances released that stimulate smooth muscle contraction, and reduce anaphylactic shock. Other work demonstrates that aqueous extract of Desmodium contains several types of active substances that act at different levels in the arachidonic acid cascade, thereby effectively and synergistically inhibiting the release of bronchoconstrictor compounds and antigens, confirming the antiasthmatic and antiallergic activity of this plant. It has been shown that three active compounds present in Desmodium: dehydrosoyasaponin I (DHS-I), soyasaponin I, and soyasaponin III are powerful specific agonists of calcium-dependent potassium channels, explaining the relaxing in vitro action on smooth muscles. These properties are promising in conditions related to asthma, ischemias, and degenerative nerve diseases.
Usages associés
Antioxidant
The radical scavenging capacity as well as the antioxidant properties can be attributed to the phenolic compounds (flavonoids) present in large numbers in Desmodium. It contains, in particular, flavones in the form of heterosides: vitexin and isovitexin. A concentration of 0.1mg/ml of a hydro-ethanolic extract of the leaves is comparable in its DPPH free radical scavenging activity to vitamins E and C. The antioxidant properties and radical trapping capacities of Desmodium could increase its therapeutic value to fight oxidative stress, responsible for inflammation and cellular degeneration. Hence, its hepatoprotective potential.
Usages associés
Immunomodulator
Desmodium appears to act as a stimulant of the leukocyte population of monocytes, cells involved in innate defense and constituting the first line of defense against pathogens. This increase in the monocyte population induced by Desmodium is an argument validating its use in infectious pathologies. Moreover, Desmodium induces a lasting depression of the IgE level, which highlights its interest in allergic pathologies, particularly pulmonary, by reducing the same allergic response. The two combined effects (monocyte increase, subsequent IgE depression) support the validation of Desmodium's traditional use in respiratory, dermatological, and intestinal infections.
Usages associés
Neurological
In vivo work conducted on mice demonstrates that ethanolic extracts of Desmodium suppress the tonic phase of seizures and death. Furthermore, it delays seizures of limbic origin induced by kainic acid. The same study shows that ethanol-water extracts slow the propagation of seizures caused by pentylenetetrazole (a substance that induces seizures at high doses) and induce analgesia and hypothermia.
Digestive Effect
In decoction, the leaves of Desmodium adscendens are used to relieve constipation in traditional medicine, particularly for their laxative properties.
Usages associés
Analgesic
In external use, Desmodium leaves, in the form of a poultice, present anti-inflammatory and anti-edematous properties that help relieve osteoarticular traumas. Its high antioxidant content (polyphenols and flavonoids) might explain this anti-inflammatory action, particularly associated with its analgesic effect in cases of back pain such as lower back pain.

Interactions
Médicaments
Cytochrome P450 substrate: interaction undefined
Desmodium has an inducing effect on CYP 2B1 and 2B2 and an inhibiting effect on CYP 2E1 (types of cytochromes P450 that play a role in liver detoxification). Intake in humans can lead to modifications in the activities of certain drugs that are metabolized by these cytochromes. Indeed, the hepatocyte is involved in the xenobiotic degradation phenomenon, and there can be overdosing or underdosing. Therefore, people with drugs with a narrow therapeutic margin that are metabolized by cytochromes P450 should be careful. These drugs have a toxic concentration close to the effective concentration, hence small variations can lead to a modification of the benefits/risks ratio. This is particularly the case for meprobamate and ethylmorphine.
