Cordia dichotoma Forst. f. bark, identified as botanical source of Shleshmataka in Ayurvedic pharmacopoeia. Present investigation was undertaken to evaluate possible antioxidant potential of methanolic and butanol extract of C. dichotoma bark. In vitro antioxidant activity of methanolic and butanol extract was determined by 1,1, diphenyl–2, picrylhydrazyl (DPPH) free radical scavenging assay. The extracts were also evaluated for their phenolic contents and antioxidant activity. Phenolic content was measured using Folin–Ciocalteu reagent and was calculated as Gallic acid equivalents. Antiradical activity of methanolic extract was measured by DPPH assay and was compared to ascorbic acid and ferric reducing power of the extract was evaluated by Oyaizu method. In the present study three in vitro models were used to evaluate antioxidant activity. The first two methods were for direct measurement of radical scavenging activity and remaining one method evaluated the reducing power. The present study revealed that the C. dichotoma bark has significant radical scavenging activity.

Launaea sarmentosa (Willd) Schultz-Bip.ex Kuntze (Asteraceae), locally known as Kulhafila in the Maldives, is a creeping herb, native to tropical Indian coastlines. According to anecdotal evidence from locals in the Maldives, the roots of this plant are used as an ingredient of a popular medicinal preparation (Hilibeys) taken by mothers after childbirth. It is also used in various other ailments in different parts of the Maldives, as well as in India. So far, there has been no scientific documentation of this plant. The only source of information available is held by natives and traditional medical practitioners. The present study was conducted on the root of L. sarmentosa for its pharmacognostical and phytochemical characteristics as per Ayurvedic Pharmacopoea of India (API) parameters. The microscopic characteristics of the root show prismatic crystals, multiseriate medullary rays, laticiferous cells, and pitted parenchyma. Qualitative analyses, such as loss on drying, ash value, pH, etc., were conducted. Preliminary phytochemical screening shows the presence of alkaloids, tannin, steroids, etc.

Linaria ramosissima (Wall.) Janch., Scrophulariaceae, a folklore plant, has been claimed for its diuretic activities by traditional practitioners. The present study was undertaken to investigate the diuretic activity of L. ramosissima leaves in albino rats. Suspension of leaf powder in 2% gum acacia was administered to experimental rats orally at doses of 450 mg/kg. The diuretic effect was evaluated by measuring the urine volume, pH of urine, and urinary electrolyte excretion. Administration of the test drug increased the urine volume in a non-significant manner, while it enhanced the urinary excretion of sodium, chloride, and potassium significantly, in comparison to the control group. From the present study it can be concluded that the leaves of L. ramosissima have a significant diuretic activity.

Jivanti (Leptadenia reticulata (Retz.) Wt. et Arn) is a well known climber used for its innumerable therapeutic properties like antioxidant, antibacterial, vasodilator, galactogogue, Jivaniya, etc., Its use in veterinary practice is tremendous due to its lactogenic effect. The Ghana (dried aqueous extract) of the whole plant was prepared and evaluated phyto-chemically by subjecting it to various tests like physico-chemical, qualitative analysis; TLC and HPTLC. Qualitative tests revealed the presence of flavonoids and TLC also inferred positive Rf value (0.30), indicating the presence of quercetin in the Ghana.

Kusha (Imperata cylindrica Beauv.) and Darbha (Desmostachya bipinnata Stapf.) are enlisted among Trinapanchamoola, which is a well-known diuretic and are individually enumerated in the Mootravirechaneeya Dashemani. The article deals with the evaluation and comparison of the individual Mootrala (diuretic) action of the two drugs in healthy volunteers. In this study, 29 healthy volunteers were divided into three groups administered with Darbha Moola Churna, Kusha Moola Churna, and placebo in each group for 14 days. The volunteers were subjected to evaluation of diuretic activity by maintaining the daily total input–output charts during the course of the study. The volunteers were advised to consume a minimum 2 l of water daily. Results show that Darbha and Kusha leaded to a percentage increase in urine volume as compared to placebo group, but the result was statistically insignificant.

Cissus repanda Vahl. belongs to the family Vitaceae, commonly known in Hindi as “Panivel,” is a large climber distributed all over India. The crushed or powder of root is prescribed by tribal people and traditional medical practitioners of Orissa for its healing properties in cases of bone fracture, cuts and wounds, swellings, and so on. In spite of its reputation, its leaves have not been investigated scientifically. The present study deals with pharmacognostical and molecular characterization by Random Amplified Polymorphic DNA (RAPD) markers and their role in laying down standardization and pharmacopoeial parameters. Genomic isolation of DNA from fresh leaves was amplified by RAPD markers. The diagnostic characters are mucilage, calcium oxalate rosette crystals, spiral vessels, and fibers. The unique bands obtained in Polymerase Chain Reaction (PCR) amplification clearly discriminated having, many bright and light bands indicating the genuinity of the plant. RAPD may serve as a complementary tool in quality control of many herbal sources.

The present study has beenundertaken to evaluate the anti-inflammatory activity of two varieties of Pippali in acute and sub-acute experimental models of inflammation in albino rats. Four different market samples of each variety of Pippali were procured from different regions of India. The samples collected from South India which have given more extractive values were selected for screening of anti-inflammatory activity. Randomly selected animals were divided into four groups of six animals each. The test drugs were administered orally at a dose of 200 mg/kg and the activity was compared with standard anti-inflammatory drugs in both models. Among the two different test samples studied, it was found that Chhoti variety of Pippali suppressed inflammation of both acute and sub acute phase, while Badi variety of Pippali only of acute phase. Thus for the therapeutic utility, Chhoti variety of Pippali may be considered over the Badi variety.

Kupeelu (Strychnos nux-vomica Linn.) commonly known as nux vomica is a poisonous plant used extensively in various ayurvedic formulations, with great therapeutic significance. Ayurveda recommended the administration of Kupeelu only after purification in different media like cow's urine (Go mutra), cow's milk (Go dugdha), cow's ghee (Go ghrita), Kanji (sour gruel), and so on. Apart from the classical methods some other methods are also adopted by the traditional practitioners using castor oil (Eranda taila), ginger juice (Ardraka swarasa), in the purification of Kupeelu seeds. In the present study an attempt has been made to purify the seeds by performing two different methods (one classical and another traditional) using Kanji and Ardraka
swarasa as Shodhana media. This study reveals that both the methods studied reduce the strychnine and brucine contents in comparison to the raw seeds as determined by high performance thin layer chromatography (HPTLC). After purification in Kanji and Ardraka swarasa, the strychnine content was reduced by 39.25% and 67.82%, respectively, and the brucine content in the purified seeds was also found to have decreased by 17.60% and 40.06%, in comparison to the raw seeds.

Ayurveda has given prime importance to Mutravaha srotas (urinary system) and Srotogata Vikaras (urinary disorders). Being a system responsible for homeostasis of fluids in the body it also detoxifies the body by eliminating certain waste products through urine. When diseased, people produce symptoms such as, increased or decreased urine production, painful maturition, formation of stones, and thereby obstructed micturition, increased frequency of micturition, and so on. There are many herbs with varied actions specifically aimed at mitigating urinary system disorders. Drugs such as Jambu, Amrasthi, and the like, reduce the increased flow of urine, and hence, are considered as Mutrasangrahaneeya, whereas, drugs like Ikshu, Kustha, and so on, increase the flow of urine, and hence, are considered as Mutravirechaneeya. There are drugs like Padma, Utpala, and so on, which impart normal color to the urine and are known as Mutravirajaneeya dravyas. Asmarighna dravyas break down the calculi and remove them through the urine. These dravyas, when used under proper direction, help in relieving the pain and apathy caused by the disease.
