Information of the key ingredients of HyperBalance.

IngredientsMain active compoundsKnown effects & possible mechanisms of actions

Apocynum (Apocynum venetum)flavonol glycosidesprotect LSP-induced heart, lung, kidney and liver injuries
quercetin, hyperinselectively inhibits neutrophil superoxide and peroxynitrite production, yet with intact bactericidal activity, preventive of LPS-induced emphysema
plant-phenol (apocynin)affects blood pressure, anti-inflammatory, anti-ischemic, anti-arthritic, antihyperlipidemic, anti-diabetic, anti-aging, antithrombic, anti-stress, anti-advanced glycation end products
triacontanol, beta-sitosterol, lupeolExert long-lasting endothelium-dependent relaxant effect via stimulating nitric oxide production, ROS-scavenging Src/PI3K/Akt Pathway
scopoletin and isofraxidin.
Isofraxidin and hyperin
Gou Teng (Uncaria rhynchophylla)indole alkaloids
rhynchophylline, isorhynchophyllineAct against hypertension, asthma, cancer, cirrhosis, diabetes, stroke, rheumatism, bradycardia, arrhythmia, sedation, neurodegeneration, epileptic seizures, drug addiction, and cerebral ischemia, coagulation, endotoxemic
triterpenesprotect cardiovascular/neural/neuroglial cells, modulate calcium and potassium ion channels and neurotransmitter transporters
flavonoidsinhibit angiotensin II induced vascular smooth muscle cells proliferation, increased NO content and NOS activity
phenolsRhy and Iso rhy have endothelium-independent vasodilatory effects via L-type Ca2+ channels and other Ca2+ pathways
phenylpropanoids
Eucommia (Eucommia ulmoides)lignanshave antihypertensive effect via regulating NO and renin-angiotensin system and direct artery relaxing effect.
flavonoids, iridoidshave antioxidant, anti-inflammatory, antiallergic, antimicrobial, anticancer, antiaging, cardioprotective, and neuroprotective properties
polysaccharidesprotect against blood pressure renal injury, inhibit renal aldose reductase overexpression, inhibit Ang II-induced mesangial cells proliferation via cycle-related genes P21 and P27, and Bax
terpenes
Heal all (Prunella vulgaris)triterpenoic acids,anti-hypertensive, anti- allergic, anti-hyperglycemic, anti-hyperlipidemic, anti-hyper cholesterol,
flavonoidsanti-inflammation via inhibition of COX-2 and iNOS expression, ROS-scavenger, anti-proliferation of vascular smooth muscle cells
phenolicsstimulate blood circulation via inhibition of Na+/K+ -ATPase, inhibit inflammatory cytokines,
diterpene, polysaccharidesinhibit ROS production, restore NO production
Senna (Cassia obtusifolia)pyridoxal, pyridoxamine, pyridoxineanti-hyperlipidemic, antihypercholesterol, anti-allergic via inhibiting histamine release,
improve SOD and NO activity, inhibit platelet aggregation
Gastrodia (Gastrodia elata)gastrodinaffects blood pressure via reducing plasma endothelin levels, inhibiting angiotensin II, aldosterone and angiotensin type 1 receptor but increasing NO and PPARγ levels
gastrodigenin restores the impaired vasorelaxation and reduced eNOS
4-Hydroxybenzaldehyde exerts anti-inflammatory and anti-angiogenic activities through inhibiting LPS-induced expression of iNOS and COX-2
2,4-Bis(4-hydroxybenzyl) phenol
Wild Chrysanthemum (Chrysanthemum indicum)dose-dependently decreased aortic blood pressure but increased coronary blood flow, renal blood flow,
induces coronary and systemic vasodilation with renal vasoconstriction
habits the inflammatory response and ischemic injury by suppressing NF-kappa and MAPKs activation
Rauwolfia (Rauvolfia yunnanensis)indole alkaloidscan significantly reduce systolic blood pressure to the same degree as other first-line blood pressure maintenance drugs
(reserpine, rescinnamine, reserpiline)
ajmaline, aricine, corynanthine
deserpidine lankanescine rauwolscine
