The Treatment of Hypertension with Nutrition, Nutritional Supplements, Lifestyle and Pharmacologic Therapies
Published in Stephen T. Sinatra, Mark C. Houston, Nutritional and Integrative Strategies in Cardiovascular Medicine, 2022
Soluble fiber, guar gum, guava, psyllium, flax seed and oat bran may reduce BP and decrease the need for antihypertensive medications in hypertensive subjects, diabetic subjects and hypertensive diabetic subjects especially when incorporated into the Mediterranean diet [2–5,367–372]. In a meta-analysis, dietary fiber intake was associated with a significant 1.65 mmHg reduction in DBP but a non-significant 1.15 mmHg reduction in SBP [367]. However, a significant reduction in both SBP and DBP was observed in trials conducted among patients with hypertension (5.95/4.20 mmHg) and in trials with a duration of ≥ 8 weeks (BP 3.12/2.57 mmHg) [367]. A recent meta-analysis of 14 RCTs with flaxseed, which is a rich dietary source of α-linolenic acid, lignans and fiber, lowered BP by 1.8/1.6 mmHg (p = 0.003) [372].

Chromolaena odorata leave decoction is usefulness in managing cough. In combination with guava leaves and lemon grass, it is used for treating malaria. It also has antidiarrheal, antispasmodic, antihypertensive, anti-inflammatory, astringent, and diuretic properties.85 Decoction of the flowers is used as general tonic, antipyretic, and heart tonic.32

Psidium guajava L., commonly known as guava, is an evergreen tree native to South America, including Brazil. In a study of González-Aguilar et al. (2004), the application of MeJa to mature green guava fruits stored at 5°C for 10 days reduced deterioration and the development of chilling injury symptoms. MeJa treatment resulted in an increased activity of LOX and phenylalanine-ammonia lyase, enzymes, which have an important role in the activation of mechanisms against different stresses, including the biosynthesis of defense secondary metabolites.

Guava leaves [Psidium guajava L. (Myrtaceae)], which contain phytochemical phenolic compounds (Morais-Braga et al. 2017), are regionally used as an alternative medicine for disinfecting the human gastrointestinal tract (Daswani et al. 2011; de Souza et al. 2014). Moreover, guava leaf extracts have astringent properties resulting from tannin phenolics (Ashok and Upadhyaya 2012) and can be utilised as a skin toner for tightening skin pores and decreasing oily skin (Pongsakornpaisan et al. 2019). Further, menthol, at various concentrations, is generally used as a cosmetic cooling agent in healthcare products (Kamatou et al. 2013). Currently, it is known that applying menthol can excite the transient receptor potential melastatin 8 (TRPM8) that can cause cutaneous vasodilation (Craighead and Alexander 2016) and increase the process of convection heat dissipation through the skin (Wong and Hollowed 2017). To date, it remains unknown whether the proven astringent effects of guava leaf extract and cutaneous vasodilation, and heat-convection of menthol can be extrapolated during the post-exercise recovery period. Specifically, there is inadequate research on the utilisation of both substances to develop alternative skincare and healthcare products suitable for post-exercise application to resolve problems associated with post-exercise perspiration without affecting heat dissipation.

Acca sellowiana O. Berg. syn. Feijoa sellowiana O. Berg. belongs to the Myrtaceae family. It is commonly known as pineapple guava or guavasteen due to its fruit’s characteristic aroma and close resemblance to guava, Psidium guajava L. of the same family1,2. The plant is native to South America but has been introduced to different climatic regions including the Mediterranean1. It is cultivated for its edible aromatic fruit and also, as ornamental trees. The introduction of Feijoa in different climates resulted in the availability of many varieties of the plant with different genotypes and chemical compositions2.

The guava leaves extraction efficiency was 12.82 ± 0.91%, and the extract possessed a dark-green color with a moisture content of 6.38 ± 0.04%, which was appropriate for further experiments. The total phenolic content in the GEE was 312.6 ± 0.14 mg GAE/g DPW. Our result was higher than that of the previous studies, which showed that the total phenolic content in the guava leaves were 53.04 ± 14.85 mg GAE/g fresh weight (Iamjud et al., 2014) and ∼110 mg GAE/g DPW (Seo et al., 2014). This could be due to the differences of the guava leaves from different region, soil and environmental conditions, and cultivation time, which result in different bioactive compounds contents.
