Research Breakdown on Asteracantha longifolia
Asteracantha longifolia (of the family Acanthaceae, synonymous the Hygrophila genera (auriculata and spinosa) as well as the Barleria genera (auriculata and spinosa)) is a traditional Indian medicine named either Kokilaaksha or Talimakhana (Ayurvedic and Unani medicine, respectively) and some lesser known names of Ikshura, Ikshugandha, and Ikkirie.
Asteracantha longifolia belongs to the Ayurveda class of 'Vajikaran' for enhancement of sexual performance, and also has uses as a general tonic, sedative, asthma, jaundice, liver ailments, and diuretic as well as various 'diseases of the blood' and inflammatory diseases such as rheumatism and edema. Traditional usage seems to recommend one ounce of the root (boiled in a pint of water until fourteen ounces remain) or two ounces of the dried leaves extracted with vinegar or water.
The plant Asteracantha longifolia appears to be a traditionally recommended blood tonic and aphrodisiac from Indian medicine, and it is also known for its supposed liver benefits
The leaves of Asteracantha longifolia contain:
The aliphatic esters 25-oxo-hentriacontanyl acetate and methyl 8-n-hexyltetracosanoate
The stems contain:
The seeds contain:
A seed oil containing linoleic acid (11%), palmitic acid (8%) and stearic acid (0.6%)
Lupeol at 0.044%
The roots contain:
In a preliminary qualitative analysis of the compounds in Asteracantha longifolia leaves the classes of steroids, saponins (0.68+/-0.12%), tannins (4.92+/-0.18%), phenolics (0.16+/-0.10%), and cardiac glycosides were found while terpenoids, alkaloids, and flavonoids were absent. Despite this, in the quantitative analysis there was a detectable alkaloid (1.14+/-0.14%) and flavonoid (0.24+/-0.19%) content.
The composition of asteracantha longifolia is not very well known at this moment in timeVitamin E.
May be slightly neuroprotective, which is thought to be associated with its antioxidative properties
Appears to have some aphrodisiac properties with prolonged ingestion, although it appears to be of comparable potency to other libido enhancing herbs in rats The suppression in bone marrow cell count was also normalized by treatment with asteracantha longifolia and elsewhere in haloperidol-induced anemic rats an ethanolic extract of the aerial parts (100-200mg/kg) given via intraperitoneal injections was able to almost normalize blood cell parameters (hematocrit, RBC count, hemoglobin) after 19 days. In rats that are not anemic and given 200mg/kg of the ethanolic extract (injections), administration of the supplement does not appear to stimulate erythropoesis and is met with a small (possibly clinically irrelevant) decline relative to untreated control.
In instances of anemia where administered chemicals can reduce red blood cell count and functionality, it appears that asteracantha longifolia can stimulate erythropoesis and normalize the differences within a few weeks. This does not work in non-anemic animals, and no studies have used oral supplemental dosages yet
Does not appear to inhibit glucose absorption In rats, administration of a water extract (at 5g/kg bodyweight) prior to glucose loading has resulted in increased glycogen storage in both the liver (108.5+/-9.5%) and skeletal muscle (57.8+/-4.2%) although an increase in triglyceride storage of adipose tissue (10.2+/-1.8%) was also noted.
While the water extract of astercantha longifolia does not appear to promote nor hinder gluconeogensis, it appears that preloading this herb before carbohydrates augments the amount of glycogen that is stored in the liver and muscle tissue Oral ingestion of 10mL/kg of a hot water leaf extract (where each mL is equivalent to 1g of plant material) in normal humans is able to reduce exposure to glucose following an oral glucose tolerance test by 25%; the drink was slightly more effective in diabetics since it reduced exposure by 36%.
There appears to be a hypoglycemic effect when this herb is coingested with dietary carbohydrates, and this is thought to be related to the deposition of carbohydrates into muscle and the liver as glycogenVitamin E and Vitamin C as reference compounds. This potency carried over to the TBS assay where the water extract inhibited 60% of MDA formation, showing another effective anti-lipid peroxidation measurement.
The water extract of the roots appears to have somewhat respectable antioxidative properties against lipid peroxidation, which nonsignificantly outperform the references of vitamins C and E This same dose caused increases in semen count associated with increased spermatogenesis.
There may be a small increase in male sex organ weight that occurs alongside prolonged usage of the herb and its libidoo enhancing effects
The alkaloids appear to be the main active componentA methanolic extract of the seeds of asteracantha longifolia appears to have hepatoprotective properties against both thioacetamide and paracetamol as well as acetominophen in rats. Protection against carbon tetrachloride (CCl4) has been noted in both mouse and rat models of hepatotoxicity. A basic water extract of the roots (50-150mg/kg) alongside CCL4 in a rat model of hepatotoxicity was able to reduce the increase in liver enzymes (ALT, AST, ALP, and LDH) as well as bilirubin; the highest dose of the root extract (150mg/kg) was comparable to the reference drug of 50mg/kg Silymarins (from Milk thistle). Elsewhere, the total alkaloid fraction of the leaves at 80mg/kg has been found to be comparable to 250mg/kg Silmyarins.
Appears to have general liver protective properties in animal studies against hepatotoxins, and the potency of this plant is either comparable or lesser than that of other reference drugs such as Milk thistle although the isolated alkaloids may be more protective and terpenoid fractions of the plant have been found to have no acute toxicity below 2000mg/kg oral ingestion in rats.
