Zimbro or common juniper (Juniperus communis) is traditionally used to treat renal suppression, acute and chronic cystitis, bladder catarrh, albuminuria, leucorrhea, and amenorrhea. These uses are mainly attributed to its bioactive composition, which is very rich in phenolics, terpenoids, organic acids, alkaloids, and volatile compounds. In the last few years, several studies have analyzed the huge potential of this evergreen shrub, describing a wide range of activities with relevance in different biomedical discipline areas, namely antimicrobial potential against human pathogens and foodborne microorganisms, notorious antioxidant and anti-inflammatory activities, antidiabetic, antihypercholesterolemic and antihyperlipidemic effects, and neuroprotective action, as well as antiproliferative ability against cancer cells and the ability to activate inductive hepato-, renal- and gastroprotective mechanisms.

1. Introduction

Natural products have an important role in the research and development of new drugs. People have always extracted natural products from several natural sources, such as marine organisms, microorganisms, animals, and medicinal plants ^[1]. The main extracts from natural products come from medicinal plants. Plant-derived products and compounds have been used worldwide since ancient times in folk medicine as remedies for several diseases, such as tinctures, teas, poultices, maintaining high prevalence in public health ^[1]^[2]^[3]^[4]. Advances in clinical research and quality control have shown a greater value of herbal medicine in the treatment and overcoming of many diseases. Recent works report promising potential regarding the use of plants in the treatment and/or prevention of several hard-to-cure diseases, such as atherosclerosis ^[5]^[6], cancer ^[1]^[2]^[3]^[7]^[8], cardiovascular diseases ^[9]^[10]^[11]^[12], diabetes ^[8]^[13]^[14], and neurological disorders ^[4]^[15]^[16], among others.

The genus Juniperus includes roughly 68 species and 36 varieties and belongs to the Cupressaceae family ^[17]. The plant Juniperus communis L., named “zimbro” in Portugal, is a shrub or small evergreen tree; a perennial and long-lived coniferous, woody pioneer and colonizing plant, adapted to low nutrient availability in soil and having one the widest distribution ranges among the different plant species ^[18]. Its population is spread globally, being the only Juniperus species found in both hemispheres, with reports of this plant in Arctic regions of Asia and North America. In Europe, the largest population is found in some parts of the Alps, Scandinavia, Poland, northwest European lowlands, and Mediterranean mountain regions ^[19]^[20]. A significant population of “zimbro” is found in the Natural Park of Serra da Estrela, Portugal, where the var. alpina is mainly found at higher altitudes and the var. hemisphaerica at lower altitudes ^[21]. The wide geographical distribution is the principal reason for the remarkable variation in the morphological characteristics and secondary metabolites’ chemical composition ^[17].

On the other hand, J. communis seeds are too bitter due to their astringency. They are rarely consumed raw, usually being dried for use as a culinary component in different parts of the world. Together with juniper berries, they are commonly burnt in temples during religious ceremonies to purify the ambient air ^[22].

Relatively to their composition, “zimbro” plant parts are mostly composed of sugars, resins, organic acids, alkaloids, terpenic acids, leucoanthocyanins and flavonoids, gums, lignins, and wax. Their aromatic oils are rich in hydrocarbons of monoterpenes (α-pinene, β-pinene, sabinene, and myrcene), diterpenes, and sesquiterpenes ^[17]^[19]^[23]^[24]^[25]^[26].

2. Scientific Classification

J. communis species belongs to the Pinopsida class, Pinophyta division, Pinales order, Cupressaceae family, and Juniperus genus. Its binominal name is J. communis L.

The Juniperus genus is one of the most diverse within the conifers, being placed in the Cupressaceae family and including more than 60 species. It presents cosmopolitan distribution with a great capacity to develop in xerophytic and salinity conditions, although it is easier to find them in high-rainfall regions ^[27]^[28]. They are dioecious trees, producing seeds every 2 or 3 years that may have a globose or spherical morphology and be dispersed by zoocoria (e.g., frugivorous birds and small mammals), which allows them to colonize new territories quickly. In addition, they can be differentiated taxonomically into three well-differentiated sections, which represent different degrees of evolution within the genus, according to genetic analyses ^[27]^[29]. The Caryocedrus section, which is considered the most ancestral from an evolutionary point of view, is limited to areas of the Peloponnese, Anatolia, and Asia Minor and is only represented by the species J. drupacea, with acicular leaves, an anchor point to the stem, and woody cones ^[30]. The Juniperus (=Oxycedrus) section has a Holarctic distribution reaching the Mediterranean; it is represented by 14 species with acicular leaves, an anchoring point to the stem, and resiniferous cones. The third section, the Sabina section, is mainly found in the northern hemisphere and mountainous areas of the African continent. However, it also has some type of resin, and is distinguished from the other ones since it has decurrent needle-like or scale-shaped leaves and juicy cones ^[31]. According to these characteristics and with the fossil record, it is thought that the diffusion point of this genus occurred in the eastern Mediterranean region, first colonizing the northern regions of the Eurasian continent, and from there passing to the American continent at least 25 My ago ^[29].

All juniper species stand out for their high content of essential oils and phenolic compounds and are largely included in the traditional medicine of different cultures throughout the planet, exhibiting a wide range of biological activities and industrial applications ^[32]. Among them, it is worth highlighting the “zimbro” (J. communis) plant, since it shows the widest distribution, being practically circumboreal ^[29]^[33]. Another remarkable characteristic of this species is the ecological plasticity supported by great genetic variability, which translates into a substantially high number of varieties with phenotypes ranging from medium-sized trees (3–4 m high) to small creeping shrubs (Figure 1) ^[27]^[29]. The populations of the Iberian Peninsula are very diverse, and due to their position, their distribution is relegated to mountainous and more humid areas with a territorial occupation in islands, thus scaping from the thermophilic and xeric character of the nonmountainous lands of the Peninsula ^[30]^[33]. Indeed, it is believed that many years ago, this territory acted as a glacial refuge for many varieties that are currently found further north; even so, the populations of var. hemisphaerica show a high degree of genetic uniqueness, while the var. alpina (also known as var. nana) is mainly distributed in the upper areas of the mountains of the Iberian Peninsula, such as the Serra da Estrela mountains. These mountains are located in the middle interior of mainland Portugal and display an oromediterranean climatic island, being an isolated population from other populations of the Central System mountains or Cantabric System mountains ^[21]^[34].

As well as other plants, J. communis also receives popular names. For example, Havusa or Matsyagandha (Sanskrit); Arar, Abahal oe Habbul (Assamese); Hayusha (Bengali); juniper berry, or common juniper (English); Palash (Gujrati); havuber or havubair (Hindi); zimbro (Portuguese); padma beeja (Kannada); hosh (Marathi); havulber (Punjabi); hapusha, abhal or arar (Urdu) ^[21]^[23].

For curiosity, and despite this plant not having a strong presence in ancient mythology, it is considered a symbol of fertility in Syria. On the other hand, in the Old Testament, it is described that the juniper has an angelic presence, which sheltered the prophet Elijah from Queen Jezebel’s pursuit. Moreover, a posteriorly biblical tale described that during their flight to Egypt, the infant Jesus and his parents used juniper to hide from King Herod’s soldiers ^[35].

3. Phytochemical Composition of Juniperus communis L.

As mentioned before, J. communis L. species are composed of a myriad of constituents, including nonessential substances, i.e., phytochemicals ^[36]. These compounds are secondary metabolites produced by plants to promote their normal cellular metabolism and offer protection against biotic and abiotic factors, and consequent oxidative injury ^[37]. Additionally, they are considered the key contributors to the organoleptic characteristics (e.g., aroma and color) and health benefits exhibited by plants ^[38]. They can be divided into five major categories (Figure 2). Although the plants’ genotype mainly influences their quantitative and qualitative composition, their levels also depend on the plant’s age, ripeness degree, cultivation techniques, geographical location, and meteorological conditions ^[39]^[40].

Figure 2. Main phytochemicals found in Juniperus communis L. ^[41].

3.1. Carotenoids and Chlorophylls

Although no studies have specifically reported the chlorophyll content of J. communis L. species, Rabska and colleagues ^[42] analyzed their total levels in fertilized and nonfertilized in both genders of this plant in autumn and winter (species not specified). The obtained data revealed nonfertilized plants had a lower concentration of total chlorophyll content than the fertilized ones (mean values of 5.0 versus (vs.) 7.4 mg/g in autumn and 3.6 vs. 4.8 mg/g in winter, respectively), and also lower amounts of total carotenoids (mean values of 0.64 and 0.95 mg/g for female and male, respectively, in autumn, and scores of 0.87 against 1.2 mg/g in winter). Focusing on gender, they observed that female plants had lower amounts of total chlorophyll compounds (values of 2.9 and 4.5 mg/g for female plants in autumn and winter, respectively, and 3.7 and 5.2 mg/g in autumn and winter, respectively, for the male ones) and carotenoid levels (values around 0.90 mg/g for female plants and around 1.0 mg/g for male, in autumn and winter, respectively). Without surprises, and regarding all the comparisons made, the authors also concluded that male and fertilized plants presented the highest levels of total chlorophyll and carotenoids (mean values of 4.3 and 1.3 mg/g, respectively).

This subclass of phytochemicals, highlighting carotenoids, possesses notable antioxidant potential and the ability to easily activate metabolic detoxification pathways, reducing the risk of appearance of several chronic and degenerative disorders ^[37]^[42].

3.2. Phenolic Compounds

Phenolics are the most predominant phytochemicals present in nature, and to date, about 10,000 different structures are currently described ^[43]. They are usually classified in (i) nonflavonoids and (ii) flavonoids ^[44]. The first ones can be further categorized into phenolic acids, including hydroxycinnamic and hydroxybenzoic acids, or in coumarins, lignans, or stilbenes ^[43]. On the other hand, flavonoids can be subdivided into isoflavones, coumestans, anthocyanidins, flavan-3-ols, flavanones, flavanonols (also called dihydroflavonols), flavones, or flavonols (Figure 2), depending on their structure ^[40]. This one comprises, at least, one phenol ring attached to one or more hydroxyl groups, and it is not only the main one responsible for dividing phenolics into different subclasses but also for conferring them a notable capacity to easily scavenge free radicals and reactive species; and to chelate metals, and in this way, counteract oxidative stress, diminish proinflammatory markers, and contribute to a healthy life state ^[43]^[45].

Focusing on phenolics found in J. communis L. species (Table 1), their levels depend on genotype, plant part, origin, age, gender, and solvent used to extract phenolics and perform the studies, but in a general way, they increase with latitude and plant age ^[42]^[46]^[47]. Additionally, male leaves and berries often present higher content in phenolic compounds than female ones ^[48].

Furthermore, and knowing the current interest in the biological potential of this plant, Brodowska et al. ^[49] conducted a study where they subjected J. communis (var. communis) L. berries to different ozone concentrations and time treatments. They verified that the treatment with ozone concentrations of 100 and 130 g/m³ for 30 min almost duplicated the phenolic content (15.47 and 12.91 mg catechin equivalent per g dry weight (dw), when compared to control (9.81 mg catechin equivalent per g dw), which consequently enhanced their antioxidant capacities positively.

Generally, the majority of phenolics reported in J. communis L. plant parts include 5-O-caffeoylquinic and quinic acids, catechin, epicatechin, amentoflavone, quercetin, luteolin, apigenin, and naringenin and their derivatives (Figure 3).

3.3. Volatile Organic Compounds (VOC’s)

J. communis L. parts, namely their essential oils, present many volatile organic compounds (VOCs) in their composition, particularly the presence of monoterpene hydrocarbons, oxygenated monoterpenes, sesquiterpene hydrocarbons, and oxygenated sesquiterpenes ^[57]^[39]. As well as other phytochemicals, their levels also depend on genotype, origin, cultivation methods, meteorological conditions, and extraction techniques. Even so, among the species, monoterpenes such as α-pinene, β-pinene, and β-myrcene are the most commonly found, followed by some sesquiterpenes compounds, namely germacrene D (Figure 4) ^[58]^[59]^[60].

Figure 4. The main volatile organic compound found in Juniperus communis L. parts.

A total of 57 different VOCs were detected in leaf ethanolic extracts (50:50, v/v), with pimaric acid being the predominant one (29.74% of total VOCs), followed by α-pinene (14.86% of total VOCs), β-myrcene (6.99% of total VOCs), bicyclosesquiphellandren (6.87% of total VOCs), and β-pinene (5.29% of total VOCs) ^[57]. On the other hand, extracts of var. communis exhibited higher percentages of limonene (26.12%), benzene (15.62%), β-myrcene (9.08%), and β-pinene (7.30%) ^[61]. Focusing on var. alpina, the predominant ones in their ethanolic extracts (50% ethanol, v/v) were δ-cadinene (12.80%), α-pinene (11.0%), germacrene D (9.30%), and borneol (8.60%) ^[62].

Regarding essential oils of their leaves, in the var. communis, α-pinene was also the most found (34.87% of total VOCs), followed by citronellyl acetate (14.26%), limonene (10.72%), and terpinolene (10.65%). Additionally, vestigial amounts (<6.21%) of ρ-cymene, elemene, cadinene, cyclohexane, cedrol, and caryophyllene were also reported ^[58]. α-Pinene was also the most abundant compound detected in different leaves of var. communis from different regions of the United States of America (USA) (66.6–75.2%) ^[63].

On the other hand, in leaves of var. communis from Serbia, sabinene was the main one reported (39.40%), followed by α-pinene (13.3%) and β-myrcene (4.70%) ^[64], whereas in var. alpina from France, limonene was clearly the most predominant (30.90%), followed by α-pinene (24.40%), β-phellandrene (12.60%), β-myrcene (3.60%), and α-phellandrene (3.60%) ^[65]. Similar percentages of α-pinene were reported on var. saxatilis (23.60%); additionally, this species was also shown to possess considerable percentages of α-cadinene (10.71%), sabinene (9.53%), germacrene D (7.25%), α-murolene (6.58%), and γ-cadinene (5.87%) ^[66]^[64].

The combination of all of these results is evidence that local origin influences the phytochemical profile. Additionally, Gonny et al. ^[65] determined the VOC profile of J. communis woods and roots of var. alpina. For woods, α-terpinyl acetate (9.10%) and α-terpineol (8.4%) were the predominant ones, while for roots, a high percentage of cedrol (37.70%) and cinnamyl acetate (11.50%) were found.

VOCs have been gaining great interest owing to their remarkable antimicrobial, antioxidant, anti-inflammatory, and anticancer properties, being able to attenuate, or even mitigate, the development of cardiovascular disorders and neuropathologies, and also ameliorate the mental state of individuals ^[67].

4. Biological Potential of Juniperus communis Linnaeus

Since ancient times, J. communis parts have been largely used as antiseptics, contraceptives, and diuretics, and as a remedy to treat colds, chest complaints, rheumatism, headaches, dermatological and respiratory ailments, and kidney and urinary infections ^[68]^[69]^[67]. Given the aforementioned, it is not surprising that this plant is a focus of continuous studies to discover its full potential.

To date, several reports have highlighted its antimicrobial, antifungal, antioxidant, anti-inflammatory, and antidiabetic potential, as well as its anticarcinogenic, hepatoprotective, neuronal, and renal effects, as described in Figure 5 and Table 2, Table 3 and Table 4 ^[70]^[68]^[57]^[52]^[71]^[72]^[73]. Next, a summary of the main studies already published concerning the health-promoting properties of this plant will be presented.
