Centella asiatica
A study from year 2005 has investigated nootropic effect of aqueous extract. The study was made in mice, extract (200 mg/kg) was given from 15. day to 30. day after birth. Effect was observed from 31. day after birth to 6. month, behaviour, biochemical and histological parameters were evaluated. Performance was improved, but there was no significant effect on locomotor activity. Activity of acetylcholinesterase in hippocampus was increased and dendritic arborization of hippocampal CA3 neurons was also increased. Extract caused significant changes in neuronal morphology and improve of brain functions in young mice.1 Similar study from year 2005 has investigated influence of ethanolical extract and its fractions on nerve regeneration, concretely axonal regeneration. According to this study asiatic acid and probably some other compounds are responsible for this effect. Results show that extract can be useful in neuron damage.2

Withania somnifera
Many studies that investigate effects of Withania on nervous system has been made in last 5 years. Some of them investigated effect on dyskinesias and Parkinsonism. In year 2002 a study on a rat model of tardive dyskinesia has been made. Glycowithanolides were isolated and used for this study. Rats got haloperidol (1,5 mg/kg i.p.) once a day for 28 days for tardive dyskinesia induction. Glycowithanolides were administered in dose of 100 and 200 mg, p.o. concomitantly with haloperidol. Glycowithanolides inhibited the induction of neuroleptic tardive dyskinesia. The dyskinesia was also attenuated by vitamin E (because of its antioxidant properties), but no effect was observed after sodium valproat administration (GABA-mimetic antiepileptic agent). The results indicate that the antioxidant effect of glycowithanolides may be responsible for the prevention of haloperidol-induced tardive dyskinesia.3 In year 2006 another study has been made, in a rat model again, the dyskinesia has been induced by reserpine. After chronic treatment with root extract of Withania somnifera (4 weeks) the dyskinesia was significantly and dose dependently (50 and 100 mg/kg) reduced, reserpine-induced memory retention deficits were reversed. Chronic reserpine treatment significantly induced lipid peroxidation and decreased the glutathion levels in the brains. Chronic administration of extract significantly and dose dependently reduced the lipid peroxidation and restored the glutathion levels.4 The antioxidant effect is the main effect in protecting the neuronal injury in Parkinson disease, the effect is dose dependent.5 A study was made and investigated the protection effect on brain in a model of stroke in rats. The rats had been pretreated with extract of Withania somnifera for 15 and 30 days, than they were subjected to focal ischaemia. After 2 hours reperfusion was allowed. After 24 hours the animals were subjected to motor performance tests and were killed and investigated. The 30 days pretreatment was effective in contast to 15 days pretreatment. The antioxidant effect of extract may be responsible for protecting the neuronal injury caused by ischaemia by stroke.6
In year 2003 some studies investigating adaptogenic and anti-stress properties have been made. The adaptogenic activity was investigated against a rat model of chronic stress, rats got Withania somnifera (25 and 50mg/kg) p.o. or Panax ginseng (100mg/kg p.o.). The results show that Withania somnifera has (like Panax ginseng) significant antistress adaptogenic activity.7 Another study used isolated 1-oxo-5beta, 6beta-epoxy-witha-2-ene-27-ethoxy-olide for investigating. Stress-related indices were evaluated (creatine phosphokinase activity, lactate dehydrogenase activity, corticosterone levels, lipid peroxidation). There was a significant decrease in levels of all observed indices.8
A study investigating nootropic effect of Withania somnifera has been made in year 2001 in mice. A root extract was administered per os in doses of 50, 100 and 200 mg/kg. It improved retention of a passive avoidance task in a step-down paradigm, reversed the scopolamine-induced disruption of acquisition and retention and attenuated the amnesia.9

Ocimum sanctum
Some studies investigating antioxidant effect of Ocimum sanctum has been made in years 2004 and 2006. The first study investigated not only antioxidant, but also neuroprotective effects in rats. For this study a methanolic extract of Ocimum sanctum leaves was used. Occlusion of bilateral common carotid arteries had been made for 30 min, than followed 45 min reperfusion. Increase in lipid peroxidation and up-regulation of superoxid dismutase activity was observed. Ascorbic acid levels were unchanged. Pretreatment with extract (200 mg/kg/day for 7 days) prevented all these processes and stabilised levels of total sulfhydryl groups during reperfusion. Long-term cerebral hypoperfusion (induced by permanent occlusion for 15 days) caused behavioral and histopathological changes (cellular oedema, gliosis, perivascular inflammatory infiltrate). Treatment with extract (200 mg/kg/day for 15 days) significantly prevented these hypoperfusion-induced functional and structural changes.10 Another study from year 2006 has shown that Ocimum sanctum has antioxidant properties. Treatment of rabbits with Ocimum sanctum decreased lipid peroxidation and increased reduced glutathione content.11
A study from year 2006 has investigated nootropic effect of Ocimum sanctum. This study was made in mice, an aqueous extract was used. A control group was treated with piracetam. The extract ameliorated the amnesic effect of scopolamine, diazepam and aging induced memory deficits, decreased transfer latency and increased step down latency significantly.12
Two studies that has been made in year 2005 has investigated effect of Ocimum sanctum on changes by noise-stress. Both studies were made in rats and an ethanolic extract was used. In first study content of acetylcholine and activity of acetylcholinesterase in brain were observed. After exposure to noise stress significant reduction of acetylcholine content and increase of acetylcholinesterase activity were observed. Pretreatment with extract for 7 days prevented the changes.13 In second study other parameters were measured (norepinephrine, epinephrine, dopamine, serotonin). Administration of Ocimum sanctum extract normalized the processes in brain and controlled the alteration of neurotransmitter levels.14

Bacopa monnieri
Effect of this plant or extract respectively on cognitive functions has been investigated in last years, many studies have been made. In year 2000 antioxidant effect of extract on brain cortex, striatum and hippocampus has been investigated in rats. The animals got the extract (5 and 10 mg/kg, bacoside A content 82%, p.o.) for 7, 14 and 21 days, the effect was compared with deprenyle (2 mg/kg, p.o.). Effect of extract was comparable to deprenyle, only by 14-days and 21-days administration there was no deprenyl effect in hippocampus in contrast to extract.15 In the same year another study has been made, this study has investigated effect on cognitive functions effected by phenytoin administration in mice. Phenytoin was administered in dose of 25 mg/kg p.o. for 14 days. Extract was administered in dose of 40 mg/kg for 7 days (it was the second week of phenytoin treatment). It was found that extract significantly decreases adverse effect of phenytoin on cognitive functions without influence on anticonvulsive effect of phenytoin.16 In year 2002 other studies have been made. One of them investigated antidepressive effect of this plant. The study was made in rats, the rats got methanolic extract in doses of 20 and 40 mg/kg, p.o. for 5 days. The effect was compared with imipramine that was administered in dose of 15 mg/kg, i.p. It was found that effect of extract is comparable with imipramine.17 In the next study effect of extract on human memory was investigated. 76 subjects in the age of 40 – 65 years were registered in this study, the study was double blind, randomised, in control group placebo was used. Different memory functions were tested and anxiety levels were measured. First tests were made before study beginning, second three months after beginning and third six weeks after end of study. The results showed significant effect of extract on new information keeping. Learning ability wasn´t induced, but there was a decrease of new information forgetting. Next observed parameters were not induced.18 In year 2003 a study investigating protective effect of extract directly on rat astrocytes culture. Cell damage rate caused by high concentration of NO (S-nitroso-N-acetyl-penicilamine was used) and cell protection rate by extract using was monitored. It was found that extract protects cells not only against damage by reactive compounds, but also against DNA damage dose dependently.19 In the same year another study has been made, in this study human fibroblasts were used. Free radicals scavenging activity and DNA damage protection of extract was investigated. Cell protection against damage and scavenging activity was found dose dependently.20
