/bo·ron/ (B) (bor´on) a chemical element, at. no. 5.

boron (B)

a nonmetallic element, whose atomic number is 5; its atomic mass is 10.81. Elemental boron occurs in the form of dark crystals and as a greenish yellow amorphous mass. Certain concentrations of this element are toxic to plant and animal life, but plants need traces of boron for normal growth. It is the characteristic element of boric acid, which is used chiefly as a dusting powder and ointment for minor skin disorders. Boric acid in solution was formerly extensively used as an antiinfective and eyewash, but the high incidence of toxic reactions and fatalities associated with these preparations has greatly reduced their use.


A trivalent nonmetallic element, (atomic number 5; atomic weight 10.81).
Alternative medicine
Boron is believed by alternative health workers to be useful in pregnancy and menopause as it increases oestrogens; they also believe in boron deficiency.

Boron-rich foods
Almonds, beans, honey, lentils, peas, peaches, pears and raisins.
Molecular biology
A mutation of SLC4A11, which encodes a transporter that regulates intracellular boron levels, results in congenital endothelial dystrophy type 2, a rare form of corneal dystrophy.
Boron is non-toxic to humans; while boron is needed for certain cellular activities, a boron deficiency state is not known to exist.

Boron is used in physics as a neutron-absorber.
Boron is a trace mineral needed for proper absorption and utilisation of calcium to maintain bone density, and may help prevent postmenopausal osteoporosis; daily supplements of boron may help retain dietary calcium, magnesium and phosphorus, and increase production of oestrogen and testosterone. It is also thought to safely promote muscle growth by body-builders.


(B) (bōr'on)
A nonmetallic trivalent element, atomic no. 5, atomic wt. 10.811; occurs as a hard crystalline mass or as a brown powder, and forms borates and boric acid. A nutritional need has been reported in pregnant women.
[Pers. Burah ]


n an element/mineral found in grains, nuts, leafy greens, and (noncitrus) fruits, used in the treatment of osteoarthritis and osteoporosis and in the prevention of prostate cancer. Precaution should be taken by women at risk for hormone-sensitive cancers and for patients who are undergoing hormone replacement therapy for the estrogen-elevating effects.


a chemical element, atomic number 5, atomic weight 10.811, symbol B. See Table 6.
